Fresh from the announcement of the incredible Hella Mega Tour yesterday, Green Day, Fall Out Boy and Weezer played a super-tiny, secret show in LA last night to celebrate their joining of forces.

The trio of rock titans hit the Whisky-A-Go-Go to perform a set each, with every band each debuting the brand-new singles they released yesterday (Father Of All…, Dear Future Self and The End Of The Game respectively) as well as an amazing collection of career-spanning singles. An exciting taste of what’s to come from next year’s worldwide Hella Mega run, that’s for sure.
