Book excerpt: Few albums in the canon of popular music have had the influence, resonance, and endurance of John Coltrane's 1965 classic A Love Supreme-a record that proved jazz was a fitting medium for spiritual exploration and for the expression of the sublime. Bringing the same fresh and engaging approach that characterized his critically acclaimed Kind of Blue: The Making of the Miles Davis Masterpiece, Ashley Kahn tells the story of the genesis, creation, and aftermath of this classic recording. Featuring interviews with more than one hundred musicians, producers, friends, and family members; unpublished interviews with Coltrane and bassist Jimmy Garrison; and scores of never-before-seen photographs, A Love Supreme balances biography, cultural context, and musical analysis in a passionate and revealing portrait.
