As a sideman, Larry Campbell has a résumé that would make any musician jealous. His long career includes eight years touring in Bob Dylan’s band; studio work with Keith Richards, Paul Simon and Willie Nelson; and a seven-year stretch as bandleader of Levon Helm’s Midnight Rambles before the drummer’s death in 2012.

Campbell shared the latter experience with his wife, Teresa Williams, a country singer from Tennessee with a rich, honeyed voice who also has worked with Emmylou Harris and Hot Tuna. Last summer the couple decided to step out of the shadows of icons and release their debut album, “Larry Campbell & Teresa Williams.”

The satisfying 11-song set runs the roots-rock spectrum as it pulls from the duo’s wealth of individual experiences. Front and center are the couple’s powerful harmonies, which shine on such Campbell-penned originals as the chugging soulful opener, “Surrender to Love,” and the lonesome ballad “Did You Love Me at All.” The album also includes a few well-chosen covers, including a fiery, deep-groove take on Rev. Gary Davis’s old gospel song “Keep Your Lamp Trimmed and Burning” and a stunning version of the Grateful Dead’s “Attics of My Life,” which features Helm’s daughter, Amy, on vocals.

Campbell is proficient on multiple instruments, including guitar, fiddle and mandolin, and during live shows the couple is backed by a tight rhythm section. After many years in diligent supporting roles, Campbell and Williams are now a taking a turn in the spotlight.
