"Born in Marseilles, France, grew up in Davis, California (with a year's side trip to Tucson, AZ.), went to college at the University of California at Santa Cruz, studying with Gordon Mumma and Peter Elsea.

In Santa Cruz he hooked up with Camper Van Beethoven, apparently for life. He moved up to San Francisco in 1989, then to Los Angeles in 1997 to work for Dane Davis at Danetracks, a film sound post production facility, then back to Oakland in 2001, where received a Master's Degree in Music Composition at Mills College, studying with Fred Frith, Pauline Oliveros, Alvin Curran, and Joelle Leandre.

While in Santa Cruz in the 1980s, he played with Camper Van Beethoven, Eugene Chadbourne and various other semi-musical projects, while in San Francisco in the 1990s with Sideways, Virginia Dare, Granfaloon Bus, Dieselhed and his own band Hieronymus Firebrain, which dissolved and reformed as Jack & Jill, which later led to various records of rock music under his own name.

While in Los Angeles, besides playing and recording with Eugene Chadbourne, he played with Clyde Wrenn (as Clyde Wrenn and the Container), with Mike Marrt's Beaumont, occaisonal shows with Mark Goodman's group, Magnet, and spent a great deal of time touring the globe with Mark Linkous' group, Sparklehorse.

Returning to the Bay Area in 2001, Jonathan began playing rock shows with his own eponymous band, as well as a newly reformed and revitalized Camper Van Beethoven. He has made several guitar-centric rock music CDs since then and has performed this music in scattered California shows, including opening slots for such acts as Built To Spill (he has also sat in with Built To Spill and Yo La Tengo onstage as a violinist!) and occasionally plays solo acoustic shows still.

In 2004 Camper Van Beethoven recorded a new studio album, "New Roman Times", their first in 15 years, and a then put out a Greatest Hits package in 2009 ("Popular Songs of Great Enduring Strength and Beauty"), both followed by much touring in the United States and Europe, which continues to this day. A new CD of Camper Van Beethoven music arrived in early 2013, "La Costa Perdida" and its companion CD, "El Camino Real" in 2014.

In addition to all of this, leaving Los Angeles and the film and music industries and studying at Mills College led Jonathan back to the world of improvisation and electronic music, and he has been performing improvised music for instruments and computer around the world, including shows in the SF Bay Area, New York, Europe and Japan.

2003 saw the CD release of several improv collaborations with notable artists such as ​Fred Frith​ and Joelle Leandre, and with Shoko Hikage, and the first of many electronic music CDs. In 2004, after various shows as both a rock and an improvising duo with Dina Emerson, Chaos Butterfly formed and began recording and touring. Several CDs have been produced worldwide, as well as performances in the US and Europe with many collaborators. Chaos Butterfly is now a moniker for Jonathan performing electronic or otherwise avant-garde improv with a host of other potential musicians.

In 2012 Jonathan relocated to Stockholm, Sweden with his family, where he currently resides. Here he has been sitting in with bands such as The Plastic Pals, and even once with Gösta Berlings Saga, working on recording his own albums and with others, including Sista Maj, an improvised rock ensemble, as well as recording, mixing and performing with the Øresund Space Collective from Copenhagen."

"Mikael Tuominen is a Finnish guitarist."

"Drummer Andreas Axelsson is a longtime member of pianist Lisa Ullén ́s critically acclaimed quartet and plays in a number of fixed and fluctuating constellations ranging from jazz and free improvised music to collaborations involving dance and electro-acoustic music. He has performed throughout Europe and Scandinavia and appears on 20 plus recordings released by labels in France, Germany, Norway, Japan, Denmark and his native Sweden."

"Per Jonas Wiberg (born 8 June 1968 in Borlänge) is the former keyboardist of Swedish progressive death metal band Opeth, and a member of Michael Amott's stoner metal band Spiritual Beggars. Wiberg toured with Opeth from the 2003 Deliverance/Damnation tour onward, and joined Opeth officially in 2005. Wiberg provided backing vocals for Opeth in addition to his keyboard duties. Before joining Spiritual Beggars he was a member of Death Organ, a band based in Borlänge. He has also fronted the band Boom Club, of the same area.

Wiberg played the keyboard in the intro to "Enemy Within" by the melodic death metal band Arch Enemy. He has also played piano on Swedish progressive rock band Anekdoten's 1993 release Vemod. In 2007, he collaborated on a project called King Hobo with Clutch drummer Jean-Paul Gaster and Kamchatka guitarist Thomas Andersson.

It was announced on 6 April 2011 that Wiberg was leaving Opeth as part of a mutual decision between him and the other band members. Since 2012 he has been a live musician for the Swedish doom metal band Candlemass as well as joining Swedish band Switchblade on selected dates as a keyboard player. In 2013 he joined Swedish trio Kamchatka as a bass player and full-time member. He plays on the Kamchatka albums The Search Goes On and Long Road Made of Gold."

"Mattias Olsson (born 9 January 1975) started his career as a classical percussionist playing in orchestras and big bands on Ekerö outside of Stockholm. As a sideline to recording and producing bands Mattias Olsson writes articles (music related) for several Swedish Magazines.

He was born in Hong Kong to Swedish parents. In 1981 he moved to Stockholm. Starting as a drummer at eight years old he started off playing in big bands, pop and classical ensembles.

When he was 17 he joined progressive rock band Änglagård. Änglagård consisted of musicians from Ekerö as well as Waxholm. The band was heavily influenced by bands such as King Crimson, Yes and Genesis but also listened to less famous bands such as Shylock, Cathedral and Yezda Urfa. Änglagård quickly became known for their instrumentation skills and their dynamic range often reminiscent of classical music. When the band started the current trend in progressive rock was to use the newest digital equipment. Änglagård decided instead to use old classic prog equipment like the Rickenbacker bass, Minimoog and the Mellotron. Änglagård recorded two studio albums in the 1990s, Hybris (1992) and Epilog (1994). They also recorded a live album called Buried Alive (1996). The title was a joke from Mattias, the worst title for a live album must be ...Buried Alive. After a long hiatus the band released their third album Viljans Öga in 2012.

He also did some sessions with White Willow and Pär Lindh.

After Änglagård, he joined Swedish pop band Pineforest Crunch who have so far recorded three albums: Make Believe, Watergarden and Panamarenko. The band's influences ranged from R.E.M, American Music Club to King Crimson and the Sundays. Pineforest Crunch had a very strong D.I.Y ethos and recorded six demos before getting signed to Abbas old label Polar. The band had a hit from the first album, "Cup Noodle Song". The single was a hit in Sweden and Japan[citation needed] and lead to intensive touring. The second album, Watergarden, was recorded in England with Radiohead producer Jim Warren. Watergarden mixed orchestral textures with Mellotrons and experimental guitars. Parallel with Pineforest Crunch, he started playing drums and occasional keyboards with Reminder.

He has since then played in numerous projects and is now active as a record producer. He has recorded albums with Deadwood Forest, Devi, Clockwork, AK-Momo, Nanook of the North, Vijaya and others.

Together with musician and composer Matti Bye, Mattias Olsson has written music for both film and theatre. In 2009 they wrote music for productions at both Dramaten and Stadsteatern in Stockholm. They have also played together at silent movie festivals and showings both in Tromsö and Stockholm. They have written and played music for Berlin, Nanook of the North and Fritz Langs Metropolis.Studio

Mattias Olsson runs his own studio outside of Stockholm called Roth Händle Studio. The studio started as a simple home studio using an Akai Dps-12 and a handful microphones. There was no plan to become a producer but as bookings started to appear albums started getting recorded. The small home studio is where the Swedish pop band Andreas & Jag started recording three albums. Andreas & Jag was Mattias Olsson and Andreas Morland. Other bands that recorded at the home studio are Pineforest Crunch and Nanook of the North. The first real location was at Finnboda Varv just outside Stockholm. At this studio location bands like Kit le fever and Clockwork recorded early EPs. The Studio has a collection of musical artifacts including claviolines, pipe organs, Stylophones, Mellotrons, Celesta, Orchestrons and Talentmakers.

In 2010 the location in Sundbyberg closed and the studio went into storage for a brief while before being relocated to Sollentuna."
