Tweaker is an American alternative rock collaboration project band founded by Chris Vrenna in the late 1990s.
Tweaker's musical style incorporates synthpop, progressive rock, modern jazz and electronica genres, and is characterized by a generally melancholy and somber sound with matching artwork.
While Vrenna and Walsh supply most instruments and electronics, many other musicians contributed to Tweaker's performances and recordings, including Robert Smith, David Sylvian, Burton C. Bell, Craig Wedren, Will Oldham, Hamilton Leithauser, Buzz Osborne, Jonathan Bates and Johnny Marr.
Unlike the band's usual synthpop, shoegaze, modern jazz, dark ambient and industrial sound, the Doom 3 theme was mainly heavy metal.
In 2004, Tweaker opened for Skinny Puppy on select dates with a full live band, consisting of Chris Vrenna (drums, percussion and keyboard), Clint Walsh (guitar and keyboard), William Faith (bass guitar) and Nick Young (vocals).
