The list of celebrity-studded benefit concerts will grow by one on May 8, when the Indigo Girls, Shawn Colvin and Steve Earle will headline a charity show in Austin, Texas. |

Additional musicians may join the concert lineup at the Backyard, contributing their efforts to aid the Zapatistas in Chiapas, Mexico. The concert site, Austin, is home to Accion Zapatista, which has protested the recent massacre of 45 Mexican citizens by paramilitary officers in the tiny town of Aeteal, Chiapas.

The charity show will close out a three-week string of live Indigo Girls shows at high schools and colleges across the South and up the East Coast. The singer-songwriters will open the tour at Logansville High School in Georgia on April 13 and finish the adolescent expedition on May 7 at Irmo High School in Columbia, S.C."(The Indigo Girls) made a conscious decision to play for their younger audience, specifically the real young ones who don't get to go to the concerts late at night," said Epic Records representative Lisa Markowitz.

Missy Elliot, Sinead O'Connor and Erykah Badu, among others will then join forces with the Indigo Girls on June 19 for the kickoff of the 1998 Lilith Fair festival in Portland, Ore. Lilith Fair vendors will sell limited edition Indigo Girls CDs featuring various live cuts and a version of "Shed Your Skin" remixed by Tom Morello of Rage Against the Machine. That hefty re-worked song should begin circulating on college radio this month, Markowitz said. (Anni Layne)
