The late, great jazz bassist Keter Betts left a monumental musical legacy and a host of friends and fans. He will be honored Friday at Jazz Night, a popular weekly venue at Westminster Presbyterian Church in Washington. The musicians paying him tribute have all worked with him and benefited from his delightful sense of humor.

Pianist Robert Redd, spokesperson for the ensemble, was a member of Keter’s trio for more than 15 years. He will be joined by Buck Hill on reeds, Steve Abshire on guitar, James King on bass, Harold Mann on drums and vocalist Alison Crockett in a program celebrating Keter’s remarkable repertoire.
