Country artists came out in droves following the tragic oil spill that damaged the Gulf of Mexico and hampered the area's tourism industry. Providing free concerts to bring consumers back to the Gulf, artists including Hank Williams, Jr., Gretchen Wilson, Lee Brice, Vince Gill and Jimmy Buffett have already lent their time and talents to the cause. Two more entertainers -- Brad Paisley and newly-announced Little Big Town -- will do their part this weekend by performing Sunday night, October 17, as part of the Concerts for the Coast series.

As previously reported, Bon Jovi and Brad will participate in two separate shows this weekend, October 15 and 17, respectively. Now, Green Day Ordinance will serve as the opening act for Bon Jovi, while Little Big Town take on the same role for Brad. Rounding out the series, Alan Jackson is scheduled to be the final act for the 'Concerts for the Coast' October 30. Alan's show, also featuring Chris Young, sold out in just 90 minutes!

For Brad Paisley, the show supports a cause in which he is already involved. His H20 tour benefits Hope Through Healing Hands, which is a charity to raise money and awareness for clean water initiatives, and something the country superstar is passionate about. "It's not all fun and games," Brad tells The Boot about his shows. "That was my intent in the beginning, to make this thing more important than just a bunch of people getting drunk on the lawn every night."

Brad and Little Big Town are all expected to participate in this year's CMA Awards, where Brad, who will both co-host (with Carrie Underwood) and perform, is nominated for three awards, and Little Big Town are up for one. The awards will air live November 10 on ABC from Nashville's Bridgestone Arena.
