The Troubadour show last night in West Hollywood, Los Angeles was full of surprises with Marilyn Manson and Machine Gun Kelly taking up some vocal duties and a fan doing so on "Pollution". Other VIPs were in the crowd too, including Billy Corgan (Smashing Pumpkins), Ra Diaz (Suicidal Tendencies), Mike Muir (Suicidal Tendencies), Derrick Green (Sepultura), Danny Lohner, Peter Katsis, Jordan Schur, Tsuzumi Okai.
