"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."

"Ben Bennett started playing music as a young child, took up the drums in middle school, and has always been attracted to improvisation. His interest in jazz moved steadily towards the more avant-guarde, then to free jazz, and onward into the world of free-improv. His current music stems mainly from various forms of free-improv: maximalist, reduced, noise, etc. A desire to get the most varied and visceral array of sounds from the simplest instruments has led to an ongoing process of distilling the drumset to its essential sound-maker, the vibrating membrane. Using extended techniques involving breath and friction, as well as the time-honored tradition of hitting things with sticks, he plays an evolving pile of frame drums, pre-tuned drum heads, metal things, tubes, and other objects that can be combined and recombined to get a variety of sounds during a performance. This set-up lends itself greatly towards being crammed in a backpack, strapped to a bike, dragged along the ground, or thrown down the stairs, generally without physical or psycological damage.

Recent projects include: bst.cr - trio with Ryan Jewell and Wilson Shook, Wrest - with Jack Wright and Evan Lipson, Rotty What - trio with Jack Wright and John M Bennett; Central Ohio War Coalition - with Mike Shiflet, Joe Panzner, and others; duos with Ryan Jewell, Jack Callahan, and Ben Hall; and solo performances."
