Well, this saddens me (more so that they are going with Feldman and not Caleb again). But, as long as they still making catchy & heavy music that doesn't sound too much like criminal, then i'll keep supporting them:)
It's weird, but I honestly don't mind the Last Breath/All Alone sound, and I hope they at least mix songs like that with the sound of This Means War. Also, fun fact, Whiting said in an interview that they've recorded 3 songs in Drop F.
