Chicago has been a mecca for all kinds of music, with acts as diverse as Cheap Trick, Etta James, 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 ?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 and recorded Nirvana's third album ?In Utero.? Later, they're joined by Cheap Trick's Rick Nielsen.
