Twenty years ago, singer Bob Geldof organized "Live Aid," a day-long, multi-city concert with the world's top entertainers that raised millions for Ethiopian famine victims. Now he's doing it again in 2005, dubbing it "Live 8" and again featuring a star-studded lineup on July 2. Country music is well-represented; Faith Hill and Tim McGraw are on the bill for the Rome concert at Circus Maximus, and Keith Urban will rock the Museum of Art at the Philadelphia show. This event is called Live 8 in recognition of the G8 summit of the world's wealthiest nations taking place in Gleneagles, Scotland, July 6-8. Organizers are hoping these free concerts will raise awareness of poverty in developing countries and pressure G8 leaders to pledge their financial support to the cause. AOL Music plans a free simulcast of Live 8, and will offer the show later on-demand. Look for additional acts to be announced at a later date. For more information, visit live8live.com
