Herbert Jeffrey Hancock (born April 12, 1940) is an Academy Award and Grammy award-winning American jazz pianist and composer. He embraces elements of rock and soul while adopting freer stylistic elements from jazz.
From Herbie, Fully Buddhist, interview by Valerie Reiss, 2007:
Through much of his diverse career, Hancock, 67, has practiced Nichiren Buddhism (pronounce nee-chee-ren), . . . Well, back in 1972, my band was playing music that required a very intuitive sense. It was an avant-garde approach to playing jazz. So it was very much in the moment and spontaneous. We had structure, but it was a very loose structure. So we went though a period when we were vegetarians because we would keep trying to find things that would help the flow of the music. I was very open at that time. [the interview went on to how Hancock then became a Buddhist, but does not clarify whether he remained vegetarian].
