Friday:
 • Savalas in Williamsburg hosts The Babymaker, an unfortunately-titled recreation of a high school dance. Recreation for some, wishful thinking for others. 285 Bedford Ave, 11 pm.
• Sundance comes to New York as BAM hosts a sampling of the festival's films. Go, but only after you've seen Just My Luck at least three times. [flavorpill]

Saturday:
 • Little kids with big guitars: The School of Rock NYC (yes, like the movie) present a Tribute to the Beatles. What's cuter than a 7-year-old rocking out to Happiness is A Warm Gun? Not much. [SoR]
• The Grand Street block party offers bands, burgers, and an excuse to get drunk outside in broad daylight. That's really all you need for an excellent Saturday. [Paper]

Sunday:
 • PSA: it's Mother's Day, so pick up the phone. Then you're free to wander to Northsix for Harry and the Potters. [flavorpill]
