Follow You Down - Gin Blossoms, probably the most well known band to come from Arizona
Jimmy Eat World is from AZ!
That's absolutely true, and it is probably a close second to the Gin Blossoms in well-known-ness, but I could be wrong, it could be the other way around. Given the quality of Arizona bands that manage to break into moderate success, it's really a shame we haven't had any for a while. There was a time when I thought a band called Dear and the Headlights - my sister was actually friends, at one point, with over half the band, seeing as how they had been attending our church for sometime (which is where they met) when they formed. They toured with bands like the Plain White T's and Mae, and later with Jimmy Eat World and Paramore, had a spot at Lollapalooza, and were on the 2009 Warped Tour. But, alas, they dissolved in 2011. Hopefully Gospel Claws - who's lead singer is the original bassist from Dear and the Headlights - will manage to break out (they played at SXSW last year).
