I'm a HUGE Sass fan. Her best work, as most others mentioned, is Rats, followed by Racine. The S.U.N. project is fantastic as well. Her late '90's stuff, Present & Hot Gossip, was more poppy...like she was going after that Lilith Fair crowd. Didn't work and she confused the fanbase she had built with her rock albums. The following two albums, Get What You Give and From Dusk Til Dawn are more rock based, albeit toned down and more bluesy.

As for S.U.N., it's a great classic rock album, kinda like Black Country Communion made two years ago. BTW, I don't think Tommy Stewart played drums on the album, just a live member as Tichy can't do both on stage.
