twenty one pilots talk fan art and Justin Bieber's pants.

twenty one pilots came to the 2013 mtvU Woodies prepared for their share of the performing duties -- the 2013 MTV Artists to Watch and Musical March Madness entrants spent most of 2013 touring the U.S. and Japan, crushing stages and blowing minds with their two-ring circus act, which includes bank-robber ski masks (that somehow manage to work in a not-terrifying way), pianos that serve as both instruments and trampolines, and pumped-up pandemonium. They only just put out their frenetic, complex Vessel album of punk poetry this past January, but out on the road -- where they're earning legions of fans who send them artwork inspired by their confessional lyrics --  Tyler Joseph and Josh Dun perfected the kind of raw, anarchistic spontaneity that only a band with an innately rebellious rock ethos can. These boys came to the Woodies prepared, which left them plenty of time to relax before the big show and... consider Justin Bieber's recent dustup with the British paparazzi.

Turns out that Tyler Joseph can totally relate to Justin Bieber's primal instinct to throw elbows: "As a dude, half of my life is walking around wanting to get in a fight." (Save it for the stage, Tyler.) He also had some sound advice for Justin -- less camo pants. I personally disagree, but then again I don't pee in a bottle, so Tyler's probably better equipped to dispense bro-to-bro tips.
