Knock Knock

Featuring string quartet and children's choir, just like The Wall. We don't need no stinkin' education, just the new Smog album (and our front teeth back).

Each Sunday, Pitchfork takes an in-depth look at a significant album from the past, and any record not in our archives is eligible. Today, we revisit Bill Callahan’s masterful 1999 record as Smog, a breakup album about discovering new ways of being in the world.

Smog's seventh full-length album, Knock Knock, proves to be singer/songwriter Bill Callahan's subtlest collection of songs yet.
