"Mommy, What's a Funkadelic?" A good question to open a game-changing debut album. The song answers its own query: A Funkadelic is a playful, soulful amalgam of screaming psychedelic riffage, deep-sea bass, wild group vocals, black liberation ideology, and unsubtle sexual innuendo. The first 30 seconds of "I'll Bet You"—neck-snapping breakbeat plus razor-sharp guitar—could define a lesser band's entire career. "What Is Soul" offers further introduction to the band's universe: "Behold! I am Funkadelic/I am not of your world."
