When Gwar was first formed, their drummer was a character named Hans Orifice. Hans was originally played by Sean Sumner but was replaced after a few shows by Jim Thompson. By the time Gwar's first album "Hell-O" was released, the character of Hans Orifice had been replaced by Nippleus Erectus, played by Rob Mosby. However, following the album's release, Mosby left the band and Pete Luchter served as Gwar's drummer under the alias Lee Beato. Luchter had to leave the band after only a few gigs due to a nervous breakdown. Shortly afterwards, Brad Roberts joined the band as drummer and created the character Jizmak Da Gusha. Roberts played drums on "Scumdogs of the Universe" even though a misprint in the pressing accredited Mosby. Roberts also played drums for Gwar spinoff bands RAWG, X-Cops and The Dave Brockie Experience. Roberts played drums for two X-Cops songs, "Beat You Down" and "Junkie," replacing Mike Dunn. He is also featured as a vocalist on the song "Barbells" on the album "You Have The Right To Remain Silent...", though he is not the album's drummer.
