Rock duo the Indigo Girls have dipped into their archives for "Rarities," an 18-track set due June 14 via Legacy. The album is highlighted by the previously unreleased tracks "Winthrop" and "Let Me Go Easy," a live version of the early Amy Ray track "Cold As Ice" and an Emily Saliers composition, "Walk Your Valley," recorded at a soundcheck.

"Rarities" sports a number of covers, from the Clash's "Clampdown" and the Rod Stewart-popularized/Crazy Horse-penned "I Don't Want To Talk About It" (from the "Philadelphia" soundtrack) to the Grateful Dead's "Uncle John's Band" (from the 1991 Dead tribute album “Deadicated”) and Vic Chesnutt's "Free of Hope."

The album also features collaborations with R.E.M. lead singer Michael Stipe and singer/songwriter Ani DiFranco, plus a remix of the 1997 track "Shed Your Skin" by Audioslave guitarist Tom Morello.

The Indigo Girls will begin a six-week summer tour June 7 in Charlotte, N.C., and will also play a Sept. 10 show at Atlanta's Chastain Park, near their Decatur, Ga., homebase.
