Four Chord Festival

I–V–vi–IV might just look like a cluster of confused Roman numerals, but to a musician, I–V–vi–IV is the chord progression that’s spawned countless chart-toppers, everything from rock hits like the Velvet Underground's “Sweet Jane” and U2’s “With or Without You” to fan-favorites of drunken karaoke stars like Blink-182’s “What’s My Age Again?” So listen for that progression at the Four Chord Festival as emo, rock, and punk bands from around the country descend on Xtaza Nightclub. Scream like a teenager to the sounds of Less Than Jake and Hit the Lights, then get political and wild with the Pittsburgh-bred Anti-Flag.
