Musical innovation is the theme for this episode. The Chicago-based Wilco has outgrown the alt-country genre with their emotional, intelligent lyrics and explorative music on releases like A Ghost Is Born and Yankee Hotel Foxtrot . Bright Eyes' music is inundated with searching melodies fleshed out with the sounds of accordion, piano, mellotron, pedal steel, vibraphone and the haunting voice of the group's only constant - 24-year-old singer/songwriter Conor Oberst.
