Keezer’s professional career began with a stellar gig as pianist in the final edition of Art Blakey’s Jazz Messengers. His previous Athenaeum performances have included appearances with bass giant Ray Brown and guitar legend Jim Hall. Keezer’s creative partnerships with Joe Locke, with whom he played an exuberant duo date at the Athenaeum in 2012, and with Hawaiian artist Keola Beamer, go back to the early 2000s. More recently, he has earned three Grammy nominations for his collaborations with Los Angeles–based vocalist Denise Donatelli, who along with Canadian-born vocalist Gillian Margot makes her Athenaeum debut in this performance.
