Chicago has been a mecca for music of all sorts, with acts as diverse as Cheap Trick, Etta James, Smashing Pumpkins, Herbie Hancock, Chicago, and Kanye West. This episode chronicles the city's musical evolution from the blues of Buddy Guy and Muddy Waters in the in the 50s and 60s, to the quintessentially midwestern rock of Cheap Trick in the 70s and the punk rock 80s as exemplified by Naked Raygun. At Electrical Audio studios, Dave Grohl and Foo Fighters connect with owner Steve Albini, a Chicago musical icon as founding member of Big Black, Shellac and more, and who produced/recorded Nirvana's third album In Utero. Later, they're joined by Cheap Trick's Rick Nielsen.
