In 2010, it seemed as if every radio station, commercial and movie included the memorable melody of Andy Grammer’s “Keep Your Head Up” from his self-titled first release.

Now, three years later, Grammer is embarking on his first headlining tour, which will hit the Old Rock House on April 11. Riding the success of his first album, as well as the resurgence of his current radio hit, “Fine By Me,” Grammer is excited to be back on tour.

“Being on tour is the best ever – literally the best thing that has ever happened in my life,” Grammer said.

Previously, Grammer toured as an opener for Train, Gavin Degraw, Colbie Caillat and Natasha Bedingfield. This spring, Grammer will be the main event, and Parachute and Andrew Ripp will be opening for the former-opener. Grammer considers the members of Parachute to be some of his best friends, referring to the spring tour as a “big sleepover.”

Headlining a tour is a change of course for Grammer, a shift he’s welcoming happily. He said that previously opening for other artists was his chance to introduce himself to the world, but now that people know his songs, a new door has opened.

“It’s the most fulfilling when you get to put on your own show,” Grammer said. “You’re kind of an appetizer outside of that.”

Grammer can be expected to sing the favorites from his album as well as covers and remixes. He promises a high-energy show with songs that he hopes everyone will want to sing along with. While he doesn’t know what to expect from this tour, he hopes for more moments like those from his tour with Train where he came on stage as his alter ego, “Andrea Grammer,” and performed with the group as a woman, to Train’s surprise.

Grammer, who previously performed at SLU, said that his favorite stop while in St. Louis was the City Museum, which he could only describe as “unbelievable.”

Fans can expect a new album from Grammer this fall as he finishes writing throughout this spring tour. While his first album told Grammer’s story of working his way up from performing on the streets, he says the new album will “definitely be different.” He doesn’t know how or in what way, since the album is still being written, but he’s excited for where he’s heading.

Tickets for Grammer’s show are available for $20 through Metrotix
