So I've been on a power-metal kick lately, having discovered the majesty of Falconer, Virgin Steele and, to a lesser extent, Kamelot. So, naturally, I'm already looking for similar bands. All the reviews point to Blind Guardian, who apparently have been around for 15+ years and were jamming PRIOR to the late 90s flower metal movement. My question is this: are they the real deal? Or, are they so much cheese? I'm interested in either Nightfall in Middle Earth or A Night At the Opera. Worthy purchases? Or over-hyped nonsense?
