Cellist Matt Haimovitz has given up traditional concert life to play in nightclubs. “No one hearing Mr. Haimovitz at CBGB could doubt his integrity and passion as he continues a 50-state tour that included a performance at a pizza palace in Jackson, Miss. Still, just as there are trade-offs when restless young listeners go to a chamber music concert at a venerated recital hall where they are expected to sit quietly and pay attention, no drinking, no eating, there are trade-offs to hearing Mr. Haimovitz play at a place like CBGB, among them his use of reverberant amplification.”
