What's bubble soccer, you ask? It's essentially regular soccer, except everyone on the field wears huge blow-up balls and collide with each other at every opportunity. You can watch Papa Roach demonstrate in the video below.
Both bands are playing Houston Buzzfest today in Texas along with PVRIS, Panic! At The Disco, Issues, Yelawolf, and more. Hopefully we can expect some video of the group's friendly competition soon.
