You’re one of the biggest rock bands around, and you’re playing arenas in Mexico City later in the week, your first shows in more than a year. What do you do to warm up? If you’re the Foo Fighters, you play a surprise pizza parlor show. On Monday, the band crammed onto the stage at Rock and Roll Pizza in Moorpark, California to play a 23-song set. Originally, it was supposed to be a set by drummer Taylor Hawkins’ cover band side project Chevy Metal, but Foo fans got the bonus plan. The band will be playing tonight and Friday at Foro Sol in Mexico City with The National, the band’s first shows since September 2012. It’s really hard to find anything to hate about Dave Grohl, especially when he keeps pulling ‘man of the people’ stuff like this. The band plan on recording their next album early next year.
