Actually, just Band of Horses, Imogen Heap, Death Cab and Spoon were on The O.C first. Even so, it make sense since both shows were produced from the same executive producer.

Nice!! Chuck was how I discovered Frightened Rabbit, Bon Iver, Band of Horses, The National, Blind Pilot, Imogen Heap, The Head and the Heart, The Naked and Famous, Death Cab for Cutie, Spoon and many more. I was basically living in a bubble in regards to music until this show came on lol

Frightened Rabbit, Vampire Weekend, and The National all were on Chuck!! the best TV show with the best music ever!!
