Polish death metallers VADER will perform a benefit show on December 11 at the Proxima Club in Warsaw in memory of the group's late drummer Krzysztof "Doc" Raczkowski (1970-2005). Other acts scheduled to appear include CETI, HATE, DEAD INFECTION, LOST SOUL, CORRUPTION, AZARATH, CHAINSAW and VIRGIN SNATCH. The bands will play there for free, to raise money to help Doc's wife and daughter.

In a March 2005 statement announcing Doc's departure from the group, VADER frontman Peter said, "Doc pretty hard tried to 'fight' against his weaknesses, which were troubles for all of us. Finaly he had not prevailed over that battle... All in all, he attempted. . . VADER today is not just a friendship anymore — it's our life with armies of man involved in music, releases and — first of all — fans waiting for shows or new albums... This is a high responsibility, not too many know about. If a person, even the most talented one, cannot stand it — [he] has to leave... That was Doc's decision as well."

In an April 2005 interview with AbrasiveRock.com, VADER guitarist Mauser elaborated on Doc's "weaknesses," stating, "He had a problem with alcohol and this is the problem. Maybe in the future, if he will be alright, he may be back in the band. Maybe someday. We will see what happens."
