Levy03 - I share the same high opinion you have of her work with Mazzy Star. That music though requires, for me, that I be in a certain mood or it can be really depressing. In the right mood, I really love it. Absolutely it is mesmerizing and trance like. I also agree on her latest project with "the warm intentions" - I was disappointed by that effort. Agree on the heat level.
Lori Carson is quite beautiful as well. I'd qualify the recommendations above: For Trespassers William, the out of print,
"Anchor", which is an outstanding debut (hope they put it back in print so others can enjoy it without paying the $ it's now fetching), and "Different Stars" would be my strong preference over their recent effort. For Lori Carson, again, earlier work seems to connect with me more strongly; Golden Palominos "Pure" and "This is how it Feels", and Lori Carson's solo album, "Everything I Touch Runs Wild".
