I think I bought the Babylon album on the basis of a review when it was released in 1969. He was known as Dr. John the Night Tripper at the time and was a somewhat mysterious figure. This was his second album, and now that I think about it I may have bought this one because I couldn't find his first, Gris-gris. I didn't know what to make of it and I never listened to it all that much, but it has stuck with me. And it's this sound and vibe that I most associate with his name, not the later more straightforward R&B stuff. I think "Babylon" is meant to represent Los Angeles. It worked then and it works now.
RIP Mack Rebennack aka Dr. John.
And now I want to hear that first album.
