My dad and I hypothesize Lenny Kravitz's sound guy was fired immediately after the set. Kravtiz clearly had issues with his earpiece, and after a shaky performance stormed off stage. His band jammed out for a while (very good) and then the set was over. We felt bad for him -- technical issues get people flustered, and he wasn't being a dick. "He was clearly frustrated," says my dad, "but he looked magnificent. He wasn't being a dick but it was definitely a 'why aren't you fixing this.'" U2 was great, it was a phenomenal show. But honestly it was such a scene we really only ever talk about Lenny.
