I was never a Dio fan, and his albums with Black Sabbath/Heaven and Hell suffer from awful, period production. I don't find them heavy, powerful, or anything positive. They annoy me more than anything. I didn't care for the major label metal sound of the 80s. To a pleasant, great surprise, the Radio City Music Hall live album has opened my eyes to those songs. I only wish everything Dio did with them had that heaviness and power. I thought Neon Nights was going to be another great treasure, but it isn't. It's better than the studio albums, but it's weak in comparison to Radio City. From what little I've seen, the Radio City DVD is also really good.
