The best cabaret shows in NYC this month

Part cabaret, part piano bar and part social set, Cast Party offers a chance to hear rising and established talents step up to the microphone (backed by the slap and tickle of Steve Doyle on bass and Billy Stritch at the ivories, plus the bang of Daniel Glass on drums). The waggish Caruso presides as host.

He’s worked with Liza Minnelli, Kylie Minogue and just about every downtown act in NYC. Now composer, pianist and performer Lance Horne hosts his own wild night of singing, drinking and dancing, strip-teasing and bad behavior at the East Village nightlife hub Club Cumming. Expect advanced show-tune geekery and appearances by Broadway stars looking to get down by the piano. Plan to sleep in on Tuesday.

The multitalented Matthew Morrison has lit up Broadway productions including Hairspray, The Light in the Piazza, South Pacific, Finding Neverland and Just in Time—but of course, he's probably best known for playing singing-club director Will Schuester on Glee. In his latest solo show, he promises to delve deeper than ever into the man behind the song and dance.

The complementary Callaway sisters—sunny Broadway belter Liz and shady-toned jazz swinger Ann—twine voices once again in a 15th-anniversary reprise of their duo show Boom!, a set of songs from the 1960s and 1970s that includes material by Carole King, Joni Mitchell, Stevie Wonder, the Beatles and the Simons Carly and Paul.

Jason Kravits is a character actor (The Practice) and clever songwriter who won notice with "Harrison," which imagined a Hamilton-like musical about the short-termed president William Henry Harrison. His extremely funny full-length show is devoted to improvisational comic songwriting based on audience suggestions—a high-wire act that is guaranteed to put a grin on your face.

As an actor, the astute Emily Bergl has distinguished herself onstage and onscreen; she also sings with real charm. On her night off from the Broadway musical Just in Time, in which she plays Bobby Darin's sister, she continues her distinguished cabaret side hustle in a set that ranges from Broadway greats like Cy Coleman and Rodgers and Hammerstein to current hitmakers like Sabrina Carpenter and SZA.

The superb Brazilian operatic baritone Paulo Szot, who made Lincoln Center audiences swoon in his Tony-winning turn as Emile De Becque in South Pacific, returns to 54 Below with a set of music drawn from musical theater traditions around the world, including Broadway and the Spanish zarzuela. Luke Frazier serves as musical director, joined by members of the American Pops Orchestra.

Actor-musicians Lauren Molina (Sweeney Todd) and Nick Cearley (All Shook Up) are not only talented at playing the cello, ukulele and glockenspiel but also at performing stripped-down versions of pop songs in their underwear, with multiple Broadway guest stars sharing their talents in the flesh. Guest hotties at this latest edition include Matt Doyle, Andrew Keenan Bolger, Andy Mientus, John Riddle, Nora Schell, Kuhoo Verma and Maria Wirries.
