"Marc Edwards (born July 23, 1949) is a free jazz drummer who has played and recorded with artists such as Cecil Taylor, Charles Gayle, and David S. Ware. His influences include Charlie Parker and Buddy Rich. He is currently playing with a project with Weasel Walter, and with his own group, Marc Edwards Slipstream Time Travel, an afrofuturistic free jazz ensemble. Many of his solo works have a science fiction theme. He also plays in the band Cellular Chaos, his first foray into rock drumming.

Edwards was raised in New York City, and did not initially take an interest in music. He dabbled with several instruments, but it was during junior high school when he was able to get out of wood shop class by playing drums that he first played the instrument.

In 1994. Edwards returned to music after a lengthy hiatus. He formed Slipstream Time Travel and released their first record, Time and Space Vol. 1. Current members are Ernest Anderson III, Takuma Kanaiwa, Alex Lozupone, Gene Janas, Alexis Marcelo. This line-up's performance at the Dizzy Gillespie Fundraiser of 2012 was described as "a climactic point in the evening's program ".

Edwards was interviewed on WKCR New York City after the release of Time & Space, Vol. 1 and Red Sprites & Blue Jets. During the 1970s, Apogee performed live on the station two separate occasions. His trio with Sabir Mateen and Hilliard Greene, performed at WKCR again just before playing at the Knitting Factory's sponsored festival, the Texaco Jazz Festival in 1997.Marc Edwards at the Silent Barn in Brooklyn in 2011

In 2013, Marc Edwards contributed a version of "Amazing Grace" to a benefit album to raise funds for Donovan Drayton's release from prison and trial. He also released a CD with his new group Sonos Gravis, which was described as "freely fused out rock that takes "free jazz" and cranks it." The album was listed as #12 on Steve Holtje's Top Jazz albums of 2013, along with his release with Slipstream Time Travel called Planet X Just Blew Up!, which was #13. The New York City Jazz Record says that "Sonos Gravis could, in fact, be the conceptual merger of the New York Art Quartet, Black Sabbath and Last Exit, though despite signposts reflecting noise and free jazz, this music has little actual precedent".

Grego Applegate Edwards described his 2014 release, Sakura Sakura, as "very vibrant free rock, a sort of Ascension in the metal zone. It is bracing. You will either gravitate towards it by predisposition or not. And that has something to do with your open mind about a free metal blast or the opposite." He says of the 2015 release, Mystic Mountain, "This may be their most anarchically exhilarating album yet!".

For many years, Edwards played only jazz drums, but recently has started playing rock and punk."

"Guillaume Gargaud (Born in France in 1979) is a composer and improvisational guitarist. He's already released about ten albums and composed many musics for contemporary dance. He lives in Le Havre in France where he also teaches music.

He started playing guitar when he was 15, after he was injured in a road accident and forced to stay home for a year. In 1997, in addition to his cabinetmaking studies where he practiced sculpture, marquetry, restoration of antique furniture and art drawing, he worked on his instrument on his own and performed in different bands. In 1999, after passing his exams he decided to dedicate himself to music and he entered the professional course of IIMA lead by Laurent Rousseau. He then studied composition, musical analysis, jazz, contemporary and improvised music. During his studies he experimented with multiple forms of music (free jazz, bebop...).

In 2003 , he became a permanent member of the artist collective Zwann eï . He composes for performances, installations, sound poetry and movies. He realises visual creations and integrates laptop ( Ableton, Max msp) in his sound research system which was until then made of pedals, analog effects and objects. His implication in the collective will give him the opportunity to discover a new vision of writing and of the interactive relationships connected to picture, body and to literature.

In 2007 he decided to stop his tours to devote himself to his solo music and to get more involved into teaching by creating some improvised music workshops. Many trips, projects, live performances and recording will follow.
