Darren Aronofsky's movies like "Black Swan" and "Requiem for a Dream" get much of their creepy edge from Clint Mansell's spine-tingling, dissonant yet ethereal scores. At this rare show, he'll perform from a big swath of his work with Aronofsky and his career as a pop musician and producer. The Orpheum, 842 S. Broadway, L.A. 8 p.m. Sat. $30-$48. laorpheum.com.
