Very nice music, until Martin made it great. But I don´t think much for almost any of their music once they´d split up.
And Madonna works hard at being a sleaze and slutt. Though I think her music really stinks. PU!
Martin's first innovation was to record them "raw" in the studio...no overdubs, no back-up of any kind except the levels mix.
4 track.
The Beatles were FAR more talented live they they were in the studio under Martin's OVERBEARING overdubs.
