April 7. Hudson Valley clarinetist and composer David Rothenberg and vocalist Timothy Hill collaborated with the late Kingston avant-garde icon Pauline Oliveros for the 2014 album by the Cicada Dream Band, which saw the three perform to the accompaniment of Rothenberg's field recordings of emerging 17-year cicadas. With the passing of Oliveros last year, Rothenberg and Hill have teamed up with Czech-American violinist and vocalist Iva Bittova to revisit the concept as the New Cicada Trio, which will make mysterious magic for the Howland Cultural Center's music-and-voice Equinox Series. (Old Timey Southern Fiddle Tunes night takes place second Tuesdays.) 8pm. $15. Beacon. (845) 331-4988; Howlandculturalcenter.org.
