Pearl Jam just announced a 2015 tour of Latin America, and with the announcement came a new publicity photo of the veteran grunge band. Upon not-too-close inspection, it struck us that the band seemed very angry in this new picture.

Frontman Eddie Vedder doesn't look too pleased that someone is taking his picture. Guitarists Mike McCready and Stone Gossard look annoyed as hell. Drummer Matt Cameron wants no part of the photo. And finally, bassist Jeff Ament looks like he's about to rip someone's head off.

So, why are Pearl Jam so angry? Well, we have some theories, and we're sharing them with you via some fun memes. Find out what's eating away at Pearl Jam by clicking through the gallery above! And check out Pearl Jam's tour dates here.
