"Fred Lonberg-Holm (born 1962) is an American cellist based in Chicago. He relocated from New York City to Chicago in 1995. Lonberg-Holm is most identified with playing free improvisation and free jazz. He is also a composer of concert works. As a session musician and arranger, he is credited on many rock, pop, and country records. Lonberg-Holm currently leads the Valentine Trio, with Jason Roebke (bass) and Frank Rosaly (drums). This jazz trio performs original compositions as well as tunes by both jazz composers (e.g. Sun Ra) and pop songwriters (e.g. Jeff Tweedy, Syd Barrett). The group released its first album Terminal Valentine, in 2007, which was reviewed by AllAboutJazz critic Nils Jacobson.

He coordinates and directs performances of his Lightbox Orchestra, an improvising ensemble with a flexible, ever-changing membership. Lonberg-Holm does not play an instrument in this group, but rather conducts its non-idiomatic improvisations via the "lightbox" and by holding up handwritten signs. The lightbox contains a light bulb for each musician which Lonberg-Holm switches on or off to suggest when they should play. Collective groups of which Lonberg-Holm is a member include Terminal 4 who released an album, in 2003, called When I'm Falling that received four and a half stars, and AMG Album Pick by Allmusic, and it was reviewed by Allmusic's Joslyn Layne, The Boxhead Ensemble, Pillow, the Lonberg-Holm/Kessler/Zerang trio (with Kent Kessler and Michael Zerang), and the Dörner/Lonberg-Holm duo (with Axel Dörner).

Among groups led by other people, he is a member of the Vandermark 5, the Joe McPhee Trio, the Peter Brötzmann Chicago Tentet, Keefe Jackson's Fast Citizens, and Ken Vandermark's Territory Band. When he lived in New York, Lonberg-Holm frequently collaborated with the rock group God Is My Co-Pilot pianist and composer Anthony Coleman as well as multi-instrumentalist Paul Duncan of Warm Ghost. In Chicago, he has worked with Jim O'Rourke, Bobby Conn (on "Llovessonngs" [1999] and "The Golden Age" [2001]), The Flying Luttenbachers, Lake Of Dracula, Wilco, Rivulets, Mats Gustafsson, Sten Sandell, Jaap Blonk, John Butcher, and a great many others.

Lonberg-Holm's concert works have been premiered by William Winant, Carrie Biolo, the Austin New Music Co-Op, Subtropics Ensemble, Duo Atypica, the Schanzer/Speach Duo, New Winds, Paul Hoskin, Kevin Norton, the E.S.P. Ensemble, and others. His scores for dance have been performed at the Brooklyn Academy of Music and Dance Theater Workshop as well as many other venues. He is a former composition student of Anthony Braxton and Morton Feldman. He performed improvised music in the role of a troubled composer who finds inspiration in the love of a couple he spots on the street in a short film for the Playboy channel."

"Jen Clare Paulson is no ordinary fiddler, she's actually a violist who has always had a wandering musical eye. Originally from Chicagoland, she relocated to Madison to get her doctorate in viola performance with a minor in jazz studies at the University. In addition to performing in regional orchestral and chamber music settings she is also a member of several new music ensembles based in Chicago - most notably Kyle Bruckmann's Wrack, who recently toured Europe and won a generous Chamber Music America grant for future projects. Highlights from JCP's musical pursuits include: studying Japanese koto in college, playing Bach cello suites on tenor banjo, transcribing tenor sax blues solos for viola and playing in string sections behind artists as diverse as Ray Charles, Olivia Newton John and Ricky Skaggs.

Jen has taken a few lessons on bluegrass fiddle with Jerry Loughney (Above the Town) and old time fiddle with Jim Becker (Caliphone); but mostly she's listening hard and making it up as she goes.

JCP teaches violin and viola at The Madison Music Foundry and works as an apprentice at Spruce Tree Music and Repair, learning to repair and restore new and vintage string instruments."

He has also appeared with Michael Moore, Ab Baars, Michiel Braam, Satoko Fujii, and Anthony Coleman. Bill Meyer (Chicago Reader): "...the impeccable logic of his lines and the richness of his tone leave you wanting more... Jackson's high-register squiggles and coarsely voiced, rippling runs push the limits of the tenor's tonal envelope." Frank van Herk, de Volkskrant (Amsterdam): "[Jackson] has an old-fashioned, warm-woolly sound, and a feeling for melodic lines that take their time in unfolding." He has been mentioned in the DownBeat Critics Poll in the Rising Star Tenor Saxophone category. Recordings are available on Delmark and Clean Feed Records."

"Peter Maunu is the archetype 21st Century musician -- a master at using technique and technology to forge great art.

The creative breadth and beauty of Peter Maunu's textural guitar work can best be appreciated by examining his musical roots. He began his career as a classical violinist and concert master, earning a scholarship to the San Francisco Conservatory of Music while still in his early teens. After hearing the groundbreaking work of Hendrix and The Beatles' "Tomorrow Never Knows", Peter became fascinated with the sonic possibilities of the guitar and it soon commanded much of his interest. His orchestral approach to playing has always infused his guitar work.

Peter's musicality and command of many styles has led to recording and live performances with an eclectic group of artists including Airto, Billy Cobham, Jean-Luc Ponty, Heart, L.A. Express, The Pointer Sisters, Wang Chung, Lou Gramm and Bobby McFerrin. In the late 70's, he and several Bay Area friends -- Mark Isham, Patrick O'Hearn, Terry Bozzio -- formed the pioneering instrumental alliance Group 87, which released two ahead-of-its-time albums. Maunu's longtime involvement with composer Mark Isham has encouraged his experimental side, leading to Peter's many contributions in film music. His solo album "Warm Sound in a Gray Field" is a showcase for his adventurous compositional style."

"Mars Williams is an open-minded musician, composer and educator who commutes easily between free jazz, funk, hip-hop and rock, Mars has played and recorded with The Psychedelic Furs, Billy Idol, Massacre, Fred Frith, Bill Laswell, Ministry, Power Station, Die Warzau, The Waitresses, Kiki Dee, Pete Cosey, Billy Squier, DJ Logic, Wayne Kramer, John Scoffield, Charlie Hunter, Kurt Elling, Swollen Monkeys, Mike Clark, Jerry Garcia, Naked Raygun, Friendly Fires, The Untouchables, Blow Monkeys and virtually every leading figure of Chicago's and New York City's "downtown" scene.

John Zorn credits Mars as "one of the true saxophone players--someone who takes pleasure in the sheer act of blowing the horn. This tremendous enthusiasm is an essential part of his sound, and it comes through each note every time he plays. Whatever the situation, Mars plays exciting music. In many ways he has succeeded in redefining what versatility means to the modern saxophone player."

In 2001 Mars received a Grammy Nomination for Best Contemporary Jazz Record with his group Liquid Soul.

Despite his busy touring schedule with Liquid Soul and The Psychedelic Furs, Mars manages to stay active on the Chicago underground improvising scene. In recent years he has toured and recorded with the Peter Brötzmann Tentet, Switchback, Full Blast, Scorch Trio, the Vandermark 5, Boneshaker, Chicago Reed Quartet and Cinghiale, teaming him with such musicians as Ken Vandermark, Hamid Drake, Michael Zerang, William Parker, Ikue Mori, Kent Kessler, Fredric Lonberg Holm, Peter Brotzmann, Joe McPhee, Paal Nilssen-Love, Ab Baars, Mike Reed, Jeb Bishop, Harrison Bankhead, Dave Rempis, Kidd Jordan and Matts Gustafson.

He performs weekly in Chicago along with Jim Baker, Steve Hunt, and Brian Sandstrom in the improvising quartet "Extraordinary Popular Delusions". As a bandleader, he continues to perform and record CDs with his own free-jazz groups, the NRG Ensemble, Witches & Devils, Slam, XmarsX, Mars Trio, Boneshaker and The Soul Sonic Sirkus which features improvising musicians and aerial circus performers. Along with Die Warsau's Van Christie, Mars has started Ratking Music, a production company focusing on music for film and television.

In addition to performing and creating music, Mars has been an educator in the field of woodwinds and jazz improvisation for over thirty years. Mars held the position of Woodwind Instructor at Bard College for two years. In the last few years Mars has presented Master classes and clinics to a number of private and public institutions including, the University of Massachusetts, Amherst, the University of Chicago, Roosevelt University (Chicago, IL), and June Collins Smith Museum of Fine Art (Auburn, AL)."
