A homage to jazz age sultriness, swagger and swing, but with brilliant originals rather than tired retreads of standards, this glorious, multi-faceted, polycultural collective— burning up jazz clubs in L.A. since 2012–is the lush brainchild of Russian-born bassist and composer/lyricist Alex Gershman. With Jane Monheit and Take 6’s Alvin Chea complementing the core “nonet,” Sasha’s Bloc’s sophomore spin winks slyly at Sinatra and Ellington while hitting cabarets, blues clubs and Dixieland-drenched streets of New Orleans during a spontaneous musical travelogue. – Jonathan Widran
