2. Van Morrison, 'Astral Weeks' (1968)
Whether you consider it Van Morrison's actual solo debut, as he does, or the 1968 follow-up to the artist-disavowed Blowin' Your Mind (whose title alone sends up a warning flare), Astral Weeks is music for the ages. Timeless and transcendent, it blends Celtic soul power, poetic blues, and bewitching jazz improvisation in an earthy gossamer alchemy never recaptured. Producer Lewis Merenstein put it in motion by hiring a trio of serious jazzmen to provide spontaneous accompaniment to Morrison's voice and guitar. Morrison recorded fine pop music both before ("Brown Eyed Girl") and after (Moondance), but the Yeats-ian title track, nostalgically sexy "Cypress Avenue," and mesmerizing "Ballerina" still move and groove like they're from another green world.
