I mentioned this morning that today is the day that John Coltrane passed away in 1967 from Wikipedia:
John William Coltrane (also known as “Trane”; September 23, 1926 – July 17, 1967) was an American jazz saxophonist and composer. Working in the bebop and hard bop idioms early in his career, Coltrane helped pioneer the use of modes in jazz and later was at the forefront of free jazz. He organized at least fifty recording sessions as a leader during his recording career, and appeared as a sideman on many other albums, notably with trumpeter Miles Davis and pianist Thelonious Monk.
There’s a neat website at JohnColtrane.com with lost of cool information and other stuff including The John and Alice Coltrane Foundation which was founded in 2001 on the 75th anniverary of his birth. So check them out along with this video from a 1965 performance in Belgium
