The Indigo Girls will release their ninth studio album, "All That We Let In," Feb. 17 via Sony's Epic Records. For the set, the Atlanta-based duo of Amy Ray and Emily Saliers reunited with producer Peter Collins, who produced their 2002 release "Become You" and 1994's "Swamp Ophelia."

Backing singer/guitarists Ray and Saliers is the pair longtime band, comprised of bassist Clare Kenny, keyboardist Carol Isaacs and drummer Brady Blade. "All" also features guest vocals by Joan Osborne on three tracks: "Heartache for Everyone," "Tether" and "Rise Up."

"Heartache" has been a regular part of the Indigo Girls live sets through much of November, as has the album's upcoming first radio single, "Perfect World." Their Dec. 4 show at New York's Bottom Line was filmed for as-yet-unannounced projects, according to their official Web site.

A full tour will be launched in support of the new album. Currently, only a four-night March 25-28 stand at Atlanta's Fox Theatre is confirmed. Those shows will feature Ray and Saliers backed by their band, as well as a symphony orchestra. The Atlanta Ballet will accompany the music with modern dance interpretations choreographed by Margo Sappington.

As previously reported, the duo is also booked to perform April 4-10 on a Western Caribbean cruise organized by Olivia, a travel service provider geared towards the lesbian community.
