Judges John Rzeznik, Sheila E. and Ian "Dicko" Dickson have narrowed down the hopefuls to 12 semifinalist bands who now take the stage to rock out in front of a studio audience for the first time. From hair bands to hip-hop and classic rockers to country crooners, see if the bands can strike the right chords both on and off of the stage as they vie for America's votes. Host Dominic Bowden will reveal America's top 10 favorite bands the following week, bringing them another step closer to securing a contract with 19 Recordings and the title of "Next Great American Band." The battle begins as the top 12 take the stage in the special two-hour "Top 12 Perform" episode of THE NEXT GREAT AMERICAN BAND airing Friday, Oct. 26 (8:00-10:00 PM ET/PT) on FOX. (IDB-103/104) (TV-TBA).
