It’s hard to find an artist who was more universally admired than Tom Petty. Though some may have sold more records than him, or won more Grammys perhaps, his pitch-perfect songwriting, tireless work ethic and fearlessness in standing up to the music industry on behalf of both listeners and artists made him a uniquely beloved figure. His death on Monday night at the age of 66—after suffering cardiac arrest in his Malibu home on Sunday night—brought forth a remarkable wave of tributes from guitarists and musicians across the musical spectrum.
