There are times in a band's career when they need a shock to the system. For whatever reason, they get stuck in a rut and lose the spark that made them what they were. Fans can hear it, and when that happens, the critics begin to grow louder. Each album becomes less beloved than the one before it, there's more talk about their prime being over, and anticipation for the future begins to wane. When this happens, there aren't many things that can be done to return a band to their former glory.
