Gulfport's 13 On began as a heavy blues-rock band in early 2005 under the name "Bottomline." They released their first self-titled album shortly before Katrina and were under contract for the Bud True Music program.
Vocalist Trent Lee, drummer Jamie Shaw, bassist Terry Kovacevich and guitarist Phillip Stegall have sinced changed the direction of the band, but their blues-rock sound remains more or less intact. Their second album "In Your Mind" was recently released, and the band has opened for such classic rock mainstays as The Marshall Tucker Band, Journey and Def Leppard.
They will perform April 26 at the 15th annual Coast Coliseum Crawfish Festival.
