"Slipstream" will be released on April 10 - her first in seven years. It will also be the first release on her own record label, Redwing Records.
"I hadn't stopped moving in a very long time so I really wanted to take a total break and not concentrate on making a new record or what I was going to do next," Raitt said. "So that was really valuable because I waited until I was really ready to come back."
The 62-year-old slide guitarist's album will feature four songs recorded with producer Joe Henry and his musicians, which she describes as experimental. The remainder of the album is self-produced with her touring band.
Raitt said she's thrilled with the resulting eclectic mix of blues, rock and soul that even includes a dash of reggae and Celtic sounds. She covers Bob Dylan's "Million Miles" and "Standing in the Doorway," and Loudon Wainwright III's "You Can't Fail Me Now" as well.
"It's just a new batch of great songs," said the Grammy-winning Rock and Roll Hall of Fame member.
