They did have a good amount of success with AOB, TWW and TOL but I honestly think the band enjoys having the lower profile. They released Retribution independently even though the had the big label support with the album before that. It sounds to me like they don't wanna deal with the all the bullshit that can come with being popular and just want to concentrate on making good music and playing for their real fans.
That set is too short though. For a headlining show it should at least be three or four songs longer. How the hell do they not play Fire From The Sky
