Query: The Controllers: Unchained!

Al Hansen: An introspectiveThe Controllers were the house band at Brendan Mullen's The Masque on Hollywood Boulevard, where they would whip an audience into a frenzy. Dripping with sweat, they were the first and last band to play that venue of the early l.a. punk scene. The Controllers were known for their girl drummers Charlie Trash in 1977 and Karla Duplantier in 78. Both brought color and photographers to shows that could be fierce. DOA Dan played his Vox Phantom bass. Johnny stingray and Kid Spike penned songs that were sardonic and testosterone induced. The Controllers played at a superfast beat, the tempo most effective in Hollywood Punk77. The band was managed by the fluxus artist Al Hansen, known as the creator of "happenings" and as the paratrooper who pushed a piano out a window in wartime Europe.
