The Indigo Girls, the folk-rock duo from Georgia, are busy working in England

on several tracks for their yet-untitled new album with the members of Irish chanteuse

Sinead O'Connor's backing band. The arrangement, a publicist for the Indigo

Girls said Tuesday, came about after discussions between them and O'Connor during

last year's woman-centric Lilith Fair summer tour in the United States. O'Connor is not

participating in the sessions, the publicist said, adding that the album could be ready for

a summer release.
