"DEPENDING on whom you ask, the Shaggs were either the best band of all time or the worst. Frank Zappa is said to have proclaimed that the Shaggs were "better than the Beatles." More recently, though, a music fan who claimed to be in "the fetal position, writhing in pain," declared on the Internet that the Shaggs were "hauntingly bad," and added, "I would walk across the desert while eating charcoal briquettes soaked in Tobasco for forty days and forty nights not to ever have to listen to anything Shagg-related ever again." Such a divergence of opinion confuses the mind. Listening to the Shaggs' album "Philosophy of the World" will further confound. The music is winsome but raggedly discordant pop. Something is sort of wrong with the tempo, and the melodies are squashed and bent, nasal, deadpan. Are the Shaggs referencing the heptatonic, angular microtones of Chinese ya-yueh court music and the atonal note clusters of Ornette Coleman, or are they just a bunch of kids playing badly on cheap, out-of-tune guitars?"
