Free Ticket TuesdayMonday: Jack's Mannequin at the Roxy

John Gilhooley/OC Weekly

​Here's a treat: We're doing a free ticket giveaway today instead of our usual Tuesday extravaganza because Jack's Mannequin is headlining! OC native, frontman Andrew McMahon, will be at the Roxy in LA on Wednesday to kick off 7-Eleven's 4-concert series (all tickets are only $7.11). Find out how to get one of three pairs of tickets after the jump.

The sold-out show has Boyce Avenue opening. The whole series is a gimmick to launch Slurpee's mixmaker contest--customize your Slurpee and "create liquid art," then post pictures on the Slurpee Facebook fan page. If you name it, you can even get a chance to get featured as a mix of the week.

Here's how to get the tickets: Follow OC Weekly's music blog, Heard Mentality on Twitter @ocweeklymusic and like us on Facebook! Once  you follow us, tweet at us and tell me why you want to go to the show. Best answer wins!
