EVENTS

Millennium Magic 11 This is the kind of event where you’d do wise to watch your wallet. Not because you’ll spend so much, but because it could disappear via sleight of hand or any other form of prestidigitation that the Magic Castle performers want to employ, thereby tricking your unwitting mind. Hosted by the one-man magic institution Rob Zabrecky, Millennium Magic 11 promises a cavalcade of tricks and wonders suitable for all ages. Each night will feature a different lineup of magicians that shan’t be trusted to follow the average laws of reality. Theatre West, 3333 Cahuenga Blvd. W., L.A. 8 p.m. Sat., 2 p.m. Sun. $15-$20. (323) 851-7977. https://www.theatrewest.org.
