Ultimately, despite their pretensions, they were a good singles band and nothing more. Morrison was too lazy and self-obsessed to last.
Ray Manzarek, on the other hand, was a solid songwriterand excellent producer. He went on to develop a number of influential LA bands such as X, and record albums for a lot of good musicians.
Robby Krieger is a talented but oddball and overlooked guitarist. He emerged from a cloud of bong smoke in the early 80s to release a ripping instrumental version of The Pretenders' Tattooed Love Boys in memorial to the death of James Honeyman-Scott. Other than that I never heard anything by him before or since.
Jim Densmore... who?
