33 1/3 is a new series of short books about critically acclaimed and much-loved albums of the last 40 years. Focusing on one album rather than an artist's entire output, the books dispense with the standard biographical background that fans know already, and cut to the heart of the music on each album. Throughout her meticulously researched, song-by-song exploration of Abba's most famous moments, Vincentelli examines with insight, wit and unabashed fanaticism everything from "Knowing Me, Knowing You"'s domestic drama to, well, the shoulder pads, tights, and foil shirts worn in the "Voulez-Vous" video. In the process, she not only makes a compelling, sincere case for all things Abba but also for pop music itself.
