Yes indeed Tyson. Pianists and guitarists are often first and foremost Blues players, if not Jazz. Guitarist Robby Krieger came out of that generation of guitarists, both American and British, almost obsessed with Blues music. However, he had an unusual (for a Rock Band guitarist) amount of Jazz in his playing as well. Pianist Ray Manzarek not so much, being pretty much a Blues player. But live I thought they had a problem (I saw them twice, in '68): Manzarek was really limited because he had to play the bass parts on the album (by session great Jerry Scheff, Elvis Presley's 70's bassist) with his left hand; those bass parts were a big part of The Doors sound and style, and keyboard bass is no substitute for a real electric bass, especially when played by as great a bassist as Scheff! I've never read why they didn't just get a real bass player, like every other Rock band of the time. The odd thing to me is how dissimilar The Doors music basically was from Jim Morrison's lyrics. By the way, Jim was a very charismatic and engaging presence on stage. A lot of sex appeal!
