Here are some songs from the great album Twelve Dreams of Dr. Sardonicus. The record does not disappoint, even with that amazing title.
Check out this live version too, with a great synth, which I can’t embed: http://www.youtube.com/watch?v=GjN8PdaoFaQ
Buy the whole album if you want to hear it. I assume it’s on all of the standard music-buying places online, and you might find it at your local record store if it’s cool.
