Founding members Stefan Lagergren, Jörgen Thullberg, and Anders Holmberg reunited for a one-off gig for the release party of the Swedish Death Metal book on January 26th, 2008. The last founding member, Johan Edlund, did not participate, stating in some interviews that he doesn't want to have anything to do with Treblinka anymore; moreover, as he said in 2008, Treblinka "was an extremely bad name". The brothers Erik "Tyrant" Gustavsson and Per "Hellbutcher" Gustavsson of Nifelheim replaced him for this show.
