Diana Lane is a backup vocalist for R&B supergroup Sister Sledge. Guitarist Donnie Dean has shared the stage with jazz luminaries like Francine Reed. Now Lane and Dean come together center-stage inside the Rhythm Room, 1019 East Indian School Road, on Wednesday, January 12, performing songs like "The Need to Be" off the CD Gimmick Free. Women get in free to see the show (sorry, fellas, you gotta cough up $3), since owner Bob Corritore says, "We love the ladies." Doors open at 8 p.m., and the music starts at 9 p.m. Call 602-265-4842 or see www.rhythmroom.com.
