He also appeared as a guest or temporary musician in Sweet Noise, Hunter, Slashing Death, Unborn, Moon, and Overdub Trio.

Originally, drum sessions for Vader's album, The Beast took place at Hertz Studio in Białystok in February 2004,[1] however, Raczkowski fell down a flight of stairs, causing arm and leg injuries.

Ultimately, the band decided to hire Vesania drummer Dariusz "Daray" Brzozowski as a session musician.

And then we had a new guy (Daray) replacing one [of] the most important persons in the band (Doc), who created Vader and its songs since the beginning.

Doc's alcohol problems eventually caused him to die unexpectedly from heart failure in August 2005.
