In 1999, Bitzcore Records out of Hamburg bought the contracts from Boomba and began to reissue Turbonegro's entire back-catalogue of albums. The year 1999 also saw the release of a posthumous live album entitled "Darkness Forever!" It released selections from two of the band's shows in Hamburg and Oslo, documenting Turbonegro's larger-than-life stage antics. Their appreciation among contemporary artists from diverse musical genres as rock, pop, punk and even black metal was displayed on "Alpha Motherfuckers", a tribute album to Turbonegro that was compiled over a span of two years and released by Bitzcore in May 2001. The lineup included, among others, Queens of the Stone Age, Nashville Pussy, Therapy?, HIM, Bela B. & Denim Girl (a.k.a. German technopop star Blümchen).
