The L.A. musical landscape is thick with options over the rapidly approaching Halloween weekend.

Beat-crazy dance aficionados can choose between the 12th annual Monster Massive at the L.A. Sports Arena and the expanded two-day HARD Haunted Mansion event at the Shrine. Indie rockers can check out stalwarts Built to Spill at the Echoplex and/or new heroes the Dirty Projectors at the Jensen Rec Center.

Public radio powerhouse KCRW has entered the Halloween party fray with “Masquerade,” a costume ball and dance party at the Park Plaza Hotel in downtown L.A. that now boasts Bay area legend DJ Shadow as the headliner.

DJ Shadow joins a lineup that already includes Swedish indie urban rock outfit Little Dragon alongside such local acts as mod folkie Sea Wolf and sunshine-poppers Edward Sharpe and  the Magnetic Zeros. A who’s who of KCRW DJs, including Liza Richardson, Jason Bentley and Garth Trinidad, will spin at the event too.

Tickets are available at KCRW.tix.com
