Deru started producing music in high school and later obtained a degree is music technology from CalArts. He now resides in LA where he composes music for televison, film, dance and performance art. Ben is a co-owner of a music and sound company called "The Track Team". Their work on "Avatar: The Last Airbender", earned an MPSE Golden Reel award nomination for best sound design in 2009. Ben collaborated on a dance score for the Paris Opera Ballet with classical composer Joby Talbot in 2008, and like his other releases, this piece embodies a synergy and culmination of various musical influences.

Deru has released music with Ghostly International, Merck, Neo Ouija, and Mille Plateaux, amoungst others. Say Goodbye to Useless will be his third album and first with Mush Records. This album comprises the aesthetics of his previous releases – moody, atmospheric sounds, haunting melodies and organic textures – but with his most mature song-writing and thumping beats to date.
