Pop-country singer Brett Young has dubbed his sound “Caliville,” indicating the intersection of laid-back rock from his native California (where he started pursuing a professional baseball career before being sidelined by an injury) and the longstanding country tradition of Nashville, where Young has recorded both of his studio albums. Hit singles like “Sleep Without You,” “Mercy,” “In Case You Didn’t Know” and the recent “Here Tonight” embody his crossover style, with a bit of Nashville twang and a bit of California sensitivity. His latest album is titled Ticket to L.A.

Young was inspired by listening to singer-songwriter Gavin DeGraw, and as Young has achieved success, DeGraw has become a personal and musical mentor. On Ticket, DeGraw co-wrote and contributed piano and vocals to the song “Chapters,” a heartfelt chronicle of Young’s journey as a musician. “That was another one of those personal validations where it felt like a huge milestone,” Young told Billboard. De Graw has been added as a co-headliner for Young’s Las Vegas concert, giving the friends the chance to perform together onstage, and bringing Young’s musical journey full-circle.
