The band kicks a 41-city headlining tour April 6 at the Hawthorne Theatre in Portland and will hit a number of well known clubs along the way including Slim’s in San Francisco, the Troubadour in West Hollywood, Calif., Emo’s in Austin, the School of Rock in Hackensack, N.J., and the Knitting Factory in New York. Joining AP through May 5 will be Chicago rockers Powerspace, who were recently signed to Fueled By Ramen and will release their first full-length album this summer.

The second half of AP’s onslaught comes courtesy of a headlining spot on the Hurley Stage of the Van’s Warped Tour. The tour launches June 28 at the Coors Amphitheatre in Chula Vista, Calif., and will make 45 stops around the country before wrapping up August 25 at the Home Depot Center in Carson, Calif.

Amber Pacific got its start as Follow Through in 2002, while founding members Matt Young and Will Nutter were still in high school. After a couple of lineup changes, the band signed to Hopeless records in 2004, and changed names to avoid legal hassles.

Their debut EP caught the attention of Warped Tour organizers, and they soon found themselves a regular fixture on the tour, building their fan-base significantly over the last three years.

Bassist Greg Strong says they owe Warped a lot.

“The Warped Tour has made us the band that we are today,” Strong said. “It taught us hard work, and I’d say at least 75 percent of our fans we made on [the] Warped Tour, because we were out there every day, working as hard as we possibly could. We were working 14 hour days.”

Truth, AP’s third full-length release, is due for release May 22.
