Age hasn't dulled Bonnie Raitt's gifts: Her first album in seven years, Slipstream, proves that she remains as soulful and expressive as ever. Producer Joe Henry pens a couple of tracks. More important, he wrings a tight sympathetic sound on her behalf from his usual backing band. Her vocals sound deeper and grittier than usual, while the supporting cast supplies a blues-rock crackle to Raitt's covers. Among the many exquisite choices are the gospel-tinged Henry/Loudon Wainwright III co-write "You Can Fail Me Now" and the greasy soul-rock of Randall Bramblett's "Down To You." The show is sold out, but there's always the Internet. Sarah Siskind opens. —Chris Parker
