Mario Brodtrager, also known as Damien Insane, used to abuse the drum kits with Drahdiwaberl, Sextiger, Dr. Shivago, Blind Petition, Desert Storm, Rising Down, Kingdom Come (with Lenny Wolf) and Skew Siskin. He joined the latter band in June 2003. Skew Siskin announced in an official statement:

""He's a real crazy bird and we feel that we made an excellent choice. His drum skills match what Skew Siskin's rhythms are about: Keith Moon meets Phil Rudd! A steady 4/4 rhythm with a hard punch or an explosive attitude with a lot of breaks — especially important for Skew Siskin's well-known rides into fields of psychedelic landscape grooves."

Brodtrager was replaced by Primal Fear-drummer Randy Black in April 2005.
