Happening Saturday

EVENTS

Long Beach Comic Con Though only in its second year, this three-day expo at the Long Beach Convention Center is quickly proving itself a worthwhile convention in its own right, and not just a means of holding over comic book enthusiasts until the main event in San Diego. More than 100 exhibitors are already on-board to represent the entire pantheon of nerd-dom including Michael McMillan (“True Blood”) on Saturday and Marvel Comics founder Stan Lee on Sunday. Long Beach Convention Center, 300 E. Ocean Blvd., Long Beach. $25 ($30 at the door). 10 a.m.-7 p.m. Sat.; 10 a.m.-4 p.m. Sun. https://www.longbeachcomiccon.com.

KCRW’s Masquerade Costume Ball Killer music and creative costumes are all but guaranteed at the ball, to be held at the neo-Gothic Park Plaza Hotel. Several of the station’s DJs will spin in five themed rooms, and turntablist Cut Chemist and rock bands the Duke Spirit and Gram Rabbit will perform. Park Plaza Hotel, 607 S. Park View St., L.A. 9 p.m.-2 a.m. Sat. $75 in advance, $85 at the door (cash only). (310) 314-4635. https://www.kcrw.com.

POP MUSIC

Of Montreal When word got out last spring that the Athens, Ga.-based glam collective would be touring with Atlanta’s rising soul goddess Janelle Monáe in September, fans of freaky independent culture jumped for joy. Two sets of indie pop’s most daring time-space continuum travelers, already known for collaborating on psychedelic funk jams, would be pushing each other toward ever greater heights of spectacle, showing clubgoers that you don’t have to be Gaga (or, to cite Kevin Barnes’ stated current influence, P-Funk) to bring a universe alive onstage. Hollywood Palladium, 6215 Hollywood Blvd., L.A. 8:30 p.m. $38.50. https://www.hollywoodpalladium.org.
