Santana even had some interesting work as late as 1992's "Milagro", but nonetheless he went off a high cliff after "Welcome", and off a much lower cliff between "Milagro" and the Arista mega-platinum atrocities. As far as Blackman, I agree that she's a good drummer, very busy and powerful, but she's a jazz drummer per se, and doesn't really leave room for other percussionists. Lear was able to do that, and I thought he was fine, though of course he's no Michael Shrieve, who was the perfect drummer for Santana (the group). And Santana (the guitarist) proved conclusively on "Swing of Delight" that he is not a jazz player per se. Don't sleep on this, which has a lot of totally unanticipated magic.
