John Coltrane was a jazz saxophonist and composer who pushed the boundaries of the genre to their absolute limit. Starting in the bebop and hard bop traditions, he famously played with Miles Davis and Thelonious Monk. His 1960 album 'Giant Steps' is a masterclass in harmonic complexity. However, it was his 1965 masterpiece 'A Love Supreme' that cemented his status as a spiritual and musical giant. The album, a four-part suite dedicated to God, blended modal jazz with avant-garde exploration. Coltrane’s 'sheets of sound' technique and his intense, lengthy improvisations influenced countless musicians across all genres. He became a figure of spiritual devotion, even being canonized as a saint in the African Orthodox Church. Coltrane’s relentless quest for musical and spiritual truth before his early death in 1967 remains one of the most inspiring journeys in the history of jazz.
