In what is quickly becoming one of Los Angeles’s most lit holiday traditions, L.A. Gives Back, presented by IHeartComix, is back for a third edition on Wednesday, December 19 at Catch One. Eight of L.A.’s most influential music curators, including Brownies & Lemonade, Mad Decent, Ninja Tune, and Emo Nite, will be programming five rooms of music. As always, all proceeds will go to benefit homeless charities here in Los Angeles.

There is also an online auction featuring such cool items as a VIP meet & greet with Grumpy Cat, a Justin Bieber signed merch bundle, a one-night stay at the Ace Hotel, and a case of ranch signed by Eric Andre, among other things. The lineup is a secret as always, but past guests have included Diplo, Party Favor, Valentino Khan, Boys Noize. You never know who might show up to spread some holiday cheer.
