Off the top of my head to add to the list:
Maroon 5, Songs About Jane - Matt Wallace home run.
Pierre Marchand is brilliant. Along with his Sarah McLachlan work don't miss The Devlins, Waiting.
Also don't miss Del Amitri, Twisted - maybe Bob Clearmountain's best of his best.
Very tough to pick an Andy Wallace favorite, just about any of them are reference standards.
And Tom Lord-Alge, another tough one. Going to go with Live, Secret Samadhi.
