When they peaked: Late 2006 and early 2007
If you got drunk in 2006, you probably heard The Fratellis. The Scottish rockers made music that sounded like Scottsmen drinking, essentially writing the perfect soundtrack for hipsters looking to party and bros trying to be cool. The formula worked amazingly... for an album.
2008's Here We Stand didn't touch Costello Music, and the formula of garage rock drinking songs wore thin by the fifteenth time you heard a similar sounding tune. They went on hiatus in 2009, ensuring that they would fade swiftly, but returned in with We Need Medicine last year. The album charted, but was ignored by most critics and most people you know.
