This week, Brad Paisley remains at No. 1 for the second straight week on Billboard's country singles chart with his latest hit, 'Old Alabama.' The song also moves up a slot on the Mediabase/Country Aircheck charts, giving him a No. 1 single on both charts this week.

'Old Alabama' is the second release from Paisley's new album, 'This Is Country Music,' which was released earlier this month. The song is the follow-up release to the album's title track, which also scored Paisley a No. 1 single. With 'Old Alabama' topping the charts, it marks the singer's 19th career No. 1 single.

'This Is Country Music' is a 15-track collection, with 12 songs co-written by Paisley. The album contains many guest performances, including a duet with Carrie Underwood ('Remind Me'), Don Henley ('Love Her Like She’s Leavin''), Blake Shelton ('Don’t Drink the Water'), Marty Stuart, Sheryl Crow, and Carl Jackson ('Life’s Railway to Heaven') and Clint Eastwood (the instrumental 'Eastwood').

Later on this week, Paisley will kick off his 2011 tour, H2O II: Wetter and Wilder. The first show of the new tour will take place on Friday, June 3 at the Farm Bureau Live at Virginia Beach in Virginia Beach, Va. Edens Edge, Brent Anderson, Sunny Sweeney, Jerrod Niemann, Darius Rucker and Blake Shelton are all joining Paisley on this leg of the new tour.
