Tickets for tonight's surprise Green Day show at the Echoplex in Los Angles have just went on sale moments ago.

The Echoplex is an extremely small venue with a maximum capacity of only 350. With the Idiot Club giving away 50 tickets, this means that only around 300 tickets are available to the general public. In the past surprise shows like this one have sold out in a matter of seconds.

Head on over to TicketFly.com now to purchase your ticket.

Update 1:07pm EST: The tickets are now sold out.

If you were unable to get a ticket you still have a couple shots, 98.7 in LA is giving away tickets all day. Tune in at 12pm, 2pm, and 4pm PST for your chance to win. KROQ is also giving away tickets every hour.

Update 2:25pm: Some commenters have mentioned that KROQ is also out of tickets. 98.7LA is still giving their away though.

Best of luck to all of you who are trying to get in tonight! You can check out more info on this show later tonight on our tour page.
