Deru is Benjamin Wynn, an electronic music producer from Los Angeles. His music is best described as an amalgamation of hip-hop, electronica and IDM. Deru started producing music in high school and later obtained a degree in music technology from CalArts. He now resides in LA where he composes music for televison, film, and dance. 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. In 2008 Ben collaborated on a dance score for the Paris Opera Ballet with classical composer Joby Talbot, and like his other releases, this piece embodies a synergy and culmination of various musical influences.

Deru has released music with Mush Records, Ghostly International, Merck, Neo Ouija, and Mille Plateaux, amoungst others. Say Goodbye to Useless will be his third album and first with Mush. 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.
