One thing I don't like on the John Lennon post-Beatles albums is the production quality. He often worked with Phil Spector and the recordings have that muddy quality. The Beatles recordings were distinguished by George Martin's production, where the recordings were very crisp and clear--you could hear all the Beatles. Apparently, John Lennon didn't like his own voice, so he was always trying to bury it under these layers of overdubs and echo effects. Paul produced his own albums and he had learned a lot from Martin, so the sound on his recordings is much better, to my ear. I like to listen to the music and hear what every musician is doing.
