Singer John Moreland was careful not to make too detailed a plan when it came time to record his new album, “High on Tulsa Heat,” which premieres today on Speakeasy. “I like doing it off the cuff and seeing what happens,” the Oklahoma roots-rocker says.

The result is 10 confessional songs laced with guitar grit as Moreland sings heartwrenching lyrics in an earthy voice that sounds worn in beyond his 29 years. He sifts through recriminations on “Losing Sleep Tonight,” wonders at the effects of nostalgia on “American Flags in Black & White” and sings about shaking off the guilt of a religious upbringing to cut loose on “Sad Baptist Rain.”

“They’re all about me, pretty much,” Moreland says. “They’re all from my own life.”

Though the album falls squarely into an Americana vein, the singer cites the do-it-yourself ethos of his punk-rock past as an essential ingredient: Moreland produced the album the album himself and his friends helped record and performed on it. That’s not the only influence from his time in the hardcore scene as a teenager.

“Nobody is afraid of lyrical honesty,” Moreland says. “You’re not supposed to shy away from confrontation or emotional extremes, so maybe that’s another thing that comes from punk.”
