Green Valley Theatre Company is the first theater group outside of New York City’s Broadway to stage this 2009 English hit—an odd play about the struggling economic woes of British youth, based in a trailer park that’s overseen by a drugged-out aging party dude. Though the lead character is written over-the-top, this production needs a bit more subterranean subtlety to flesh him out. F, Sa 8pm; Su 7pm. Through 6/30. $18. Green Valley Theatre Company at The Grange Performing Arts Center, 3823 V St.; (916) 736-2664; www.greenvalleytheatre.com.
