For our final album of the year, we look at Sonic Highways, a special project by the Foo Fighters, featuring eight tracks recorded in eight studios in eight different cities, all to commemorate—you guessed it—their eighth album. The project also serves as a companion to their HBO television series, Foo Fighters: Sonic Highways, which debuted on October 17th, 2014. Also stick around for a followup conversation on music idolatry: the types of idols we venerate, and the responsibilities that go with it.
