A '00s supergroup formed around the talents of indie rock giants Conor Oberst and Mike Mogis (Bright Eyes), M. Ward (She & Him), and Jim James (My Morning Jacket), the Monsters of Folk were conceived in 2004 out of onstage collaborations and backstage hootenannies while the four musicians were on tour with their respective bands and solo projects. Their live shows would become stuff of legend, as the band members were known to switch personas and instruments at the drop of a hat. While members of this cheekily titled "supergroup" may come from the more folkish end of indie rock, the Monsters of Folk's style falls squarely in the "classic rock" camp.
