In anticipation of Valentine's Day, Rochesterians have a pair of opportunities to tear up the dance floor: Groove Juice Swing's Sweetheart Dance, and the Gay Alliance's annual fundraiser Red Ball.

Groove Juice Swing, Rochester's authority on swing dancing and Lindy Hop, is hosting its Fifth Annual Sweetheart Ball. Live accompaniment will be performed by Michael Gamble & the Rhythm Serenaders, and a free photo booth will be available to document a romantic night of swing dancing. Those with two left feet and no sense of rhythm are always welcome, but might want to take advantage of the free lesson at 7:30 p.m. No experience necessary.  The 5th Annual Sweetheart Ball will be held on Saturday, February 7, at the Memorial Art Gallery, 500 University Avenue. 7:30 p.m. to 12:30 a.m. $16-$20. groovejuiceswing.com.

The Gay Alliance of the Genesee Valley is putting on its annual fundraising ball and community dance, inspired by cultural dynamism of the age of the Flappers. The Gay Alliance will host a fantastic night of costumes and dance, augmented by hors d'oeuvres and sweets, a cash bar, an extensive raffle, and "best dressed" awards. Costumes are not required. The Red Ball is scheduled for Saturday, February 7, at Diplomat Banquet Center, 1956 Lyell Avenue. 7 p.m. $20-$30. gayalliance.org/events/redball.
