Garth Brooks will be the first artist to sell his music exclusively at Wal-Mart and its Sam's Club stores, it was announced Friday (Aug. 19). Brooks, who has ownership of his master recordings, ended his contract with Capitol Records in June. In making the announcement, Wal-Mart vice president David Porter said, "We understand the Wal-Mart customer and know that bringing them Garth Brooks exclusives in the upcoming years is something that'll excite them as much as it excites us." Brooks is expected to release a multiple-disc boxed set with previously unreleased material, according to Billboard. He has said he'll remain retired from the music business until his youngest daughter graduates from high school in 2015.
