Up Ahead, released in February, is looking like the kind of album that could bring Travis Linville acclaim similar to what fellow Oklahomans John More-land and John Fullbright have been enjoying lately. Or Parker Millsap, whom Linville once taught to play guitar. Long in his corner, however, has been Hayes Carll, who had a front-row seat to the Tulsa-based Linville’s talents as the guy who paid him to play guitar for more than a decade. (Linville, Carll once said, is “criminally underrated.”) Up Ahead isn’t quite as scruffy as Linville’s former employer; its self-assured, thoughtful tunes flash hints of ’70s greats like Paul Simon and Jackson Browne, thanks in large part to Linville’s crystal-clear tenor. If things keep up like this — the new album spurred Rolling Stone to put Linville on its latest “10 Country Artists You Need to Watch” list back in March — he could easily show the same sort of staying power.
