May 19. Hudson hits Hudson! New York pianist and composer Steve Hudson’s improv-heavy style embraces jazz, blues, folk, tango, and modern classical. The Steve Hudson Chamber Ensemble, which here visits the Hudson Opera House, is composed of violin, cello, piano, and drums. On its acclaimed recent album, Galatic Diamonds, the band explores lengthy, through-composed works as well as sparser, more minimal pieces that at times recall the sounds of fellow world/jazz/contemporary classical travelers Tin Hat Trio. (“Alone Together” features works for piano and voice May 5; the Chris Tarry Trio jams May 26.) 8pm. $18, $20. Hudson. (518) 822-1438; Hudsonoperahouse.org.
