I agree that the new Bonnie Raitt is excellent. It actually sounds like the old Bonnie Raitt. Haven't heard the other one mentioned.
Meldhau, Raitt
2 new albums that help make the audiophile life worthwhile: Brad Mehldau's "Ode", and Bonnie Raitt's "Slipstream". Brad sounds better than ever...nice cymbal tone and great balance on cool tunes, and Bonnie, well Bonnie is a national treasure at this point and even uses a fave of mine, Bill Frisell.
