Thanks to the surprise radio airplay of "Don't Eat that Yellow Snow," Apostrophe introduced a whole new audience to the music of Frank Zappa in the early '70s. Like its companion set, Over-Nite Sensation, this album found Zappa producing highly polished jazz-rock, mixing tales of absurd characters with musical showmanship and snarling guitar work. The first half of the album is a sort of mini-concept album, relating the adventures of an Eskimo named Nanook, and the second half features such Zappa classics as "Cosmik Debris" and "Stink-Foot." --Andrew Boscardin
