Angus, Thongs & Full Frontal Snogging, Griffin Theater, through May 19. Huge hit again extended! Georgia, 14, learns to snog (kiss) and gets the boy in the band in this breezy, fast, slight delight, imaginatively staged with a cast of attractive newcomers. (Abarbanel)

Blue Man Group, Briar Street Theatre, open run. The 7-year old Chicago phenomenon continues its robust run with two new pieces: one on rock star moves, and the other a truly inspired riff on the increasing encroachment of the Internet on life and art. (Reed)

Crowns, Goodman Theatre, through April 11. It’s a musical revue, it’s a fashion show, it’s cultural history and the Goodman production delivers all three in jubilant abundance. Put on your hat, shout a hallelujah, and catch this celebration before it leaves town. (Barnidge)

No Exit, Burning Doll Theatre at Springman Studios, through April 23. Not so much a performance as an improvised re-enactment, yet Sarte’s classroom classic survives with all its existential themes intact. Has Jean-Paul Sartre become mainstream culture? (Barnidge)
