Knock Knock

"Knock Knock" is the seventh album by Smog (the alias of Bill Callahan), released in January 1999 on Drag City and by Domino in Europe. The album is the fourth and final collaboration with the producer and musician Jim O'Rourke. Knock Knock elaborates Callahan's sound and provides twists and edges to the folky style of its predecessor. "Held" was the first single, followed by "Cold Blooded Old Times", which later appeared on the High Fidelity film soundtrack, thereby attracting some attention to Callahan's work.
