The group recently met their goal of providing clean water to 1,000 African communities through the organization they founded, Blood: Water Mission, and its 1,000 Wells Project. They're celebrating the milestone with a benefit concert in Nashville on May 10.

Lead singer Dan Haseltine says it was a «lofty goal» when they started out. But over five years, they ended up raising nearly $7 million for water and sanitation projects as well as hygiene training. Tickets for the Well: Done Celebration go on sale Saturday. Jars of Clay has sold more than 6 million albums, won three Grammys and had 17 No. 1 hits, including their breakout song, "Flood."
