Brad Paisley has moved up the release date of his next album , This is Country Music, to May 23rd due in large part to the success of the debut single, "Old Alabama." The 15-song collection features a handful of guest artists including Alabama, Carrie Underwood, Blake Shelton, The Eagles' Don Henley, actor Clint Eastwood and a collaboration with Marty Stuart, Sheryl Crow and Carl Jackson.
