I recently bought David Gilmour's solo disc - On An Island. It's an amazing CD. Mellow, but very mellow Floyd like with some great Gilmour signature guitar work and vocals. Sounds like it could have been from The Dark Side of the Moon era.
I highly recommend it if you were ever a Floyd fan. Not much bass work on it to speak of, typical for a guitarist from the time.
I also think that Gilmour is an unsung guitarist as he really is not a flashy player like Beck or Clapton, but his sound is unmistakable.
I put him in the Santana boat in that respect.
