When country singer Brett Eldredge opened for Luke Bryan at Progressive Field last summer, he successfully won the audience over with his 45-minute set that featured hits such as “Superhero” and the poppy “Love Someone,” a tune the benefited from the exuberant “uh-huhs” in its chorus. His spot-on cover of Train’s “Drops of Jupiter” showed off his sharp pop sensibilities. Expect something similar when Eldredge, who's on tour in support of last year's Sunday Drive, comes back to town tonight as a headliner. Morgan Evans opens the show, which begins at 7:30 at Jacobs Pavilion at Nautica. Consult the Live Nation website for ticket prices and more info.
