Have you ever felt betrayed by a band? Sometimes a band you love changes so much, you don't even know who they are anymore! That's exactly what happened to Jason with Def Leppard. We take a look at On Through The Night, writing to trends vs. writing timeless music, the music industry being scared to let bands evolve after finding success with "their thing," and so much more.
