"Happy anniversary," Brian Henneman shouted as the Bottle Rockets took the stage, launching into the heavy, bitter lament about a romantic relationship gone wrong. But his announcement had a double meaning: This year marks the St. Louis band's 15th anniversary, and vocalist Henneman, guitarist John Horton, bassist Keith Voegele, and drummer Mark Ortmann are celebrating by playing just 15 shows this year. At the end of the limited tour, they're giving away a custom-designed electric guitar and 'Bottle Rockets for Life' — all the merchandise and concert tickets a fan could hope for.
