You can find anything in San Francisco. One thing you need to go and find is the Church of John Coltrane – An African American congregation built around the spiritual awakening of John Coltrane and his subsequent album, Love Supreme.
This is not a big church like Glide or the like, it is small, it is a serious thing, and it is a seriously awesome way to go to church on a Sunday. You will see members with their saxophones in the congregation playing along with the band. It is a spiritual jam session like no other. Yes, it is a tight, small congregation but they are welcoming and happy to have you there to see what they are about. Now the service is 5 hours long. You do not have to stay for the whole thing. Just be respectful when you arrive and leave- because even though it is a full-on jazz throw down, it is still their church.
There is an awesome video dedicated to the celebration of the 5oth anniversary of the album.
