As the sole surviving member of the prog rock group Emerson Lake & Palmer, drummer Carl Palmer has felt compelled to keep the band’s legacy alive. With that in mind, he’s put together a tribute show of sorts that he’s dubbed Welcome Back My Friends — The Return of Emerson Lake & Palmer. It features live footage of the late Keith Emerson and Greg Lake on massive video walls alongside Palmer and his band as they play live. Palmer and Co. perform tonight at7:30 at the Lorain Palace Theatre.
