Even after surpassing 70 years in his musical life, Sadao Watanabe continues to move audiences worldwide as a lifelong, active performer. This time, returning for about a year after last year’s well-received performance, the six-member “Sadao Watanabe Group”—featuring Watanabe on alto saxophone along with keyboards, electric guitar, electric bass, drums, and percussion—reassembles. The program, titled after the 1984 landmark album “RENDEZVOUS,” offers an exquisite, relaxed space woven by a richly varied palette of sounds that freely change, to be enjoyed to the full.
