April 20. Germany’s Adrienne Haan is one of the brightest torchbearers of her homeland’s cabaret tradition, a lineage that harks back to Berlin’s Weimar Era. However, her new show, which here saunters into the Kaatsbaan International Dance Center, focuses on our own Great American Songbook. Titled “’Til the End of Time,” the evening is a “swinging show accompanied by a four-piece band that promises to take the audience on a flight of a lifetime.” Time to bust out the silk and sequins. (Babette Hierholzer performs with the Northern Dutchess Symphony Orchestra April 15; Jennifer Muller/The Works dance May 5.) 7:30pm. Call for ticket prices. Tivoli. (845) 757-5106; Kaatsbaan.org.
