Garth Brooks is going back to his roots with a new, four-disc box set of the music that shaped him.
Brooks revealed the new project at the tail end of a GAC special Saturday. Called Blame It All on My Roots: Five Decades of Influences, the set will separate those influences into stylistically themed discs titled Country Classics, Classic Rock, Blue-Eyed Soul and Melting Pot, according to The Music Universe.
The set will include covers of Jerry Lee Lewis' Great Balls of Fire and Marvin Gaye's I Heard It Through the Grapevine, Cat Stevens' Wild World and Simon & Garfunkel's Mrs. Robinson, along with songs made famous by James Taylor, Gladys Knight. Brooks' wife, Trisha Yearwood, will appear on the project and duet with him on a remake of Conway Twitty and Loretta Lynn's 1971 hit After the Fire Is Gone.
The collection will be available exclusively through Walmart beginning Nov. 19.
Brooks has performed many of the songs at his solo concerts at the Wynn Las Vegas, where he has played since 2009. Brooks' final Wynn show will air as the two-hour Garth Brooks: Live in Las Vegas special Nov. 29 (9 p.m. ET/PT, CBS).
Brooks has been in semi-retirment since 2001, but his oldest daughter will graduate from high school next year, leading to speculation about a full-scale comeback that could include new music and a tour.
