I would not have known how to classify the music of Aurelio Voltaire Hernández before reading about the man online. While several categories are listed on his Wikipedia article, my favorite is something called dark cabaret. Incidentally, that puts his art in the same genre as two other favorites of mine, IAMX and Tom Waits.
One of his popular hits featured in an episode of the 2000’s era cartoon “Billy and Mandy”. Called “BRAINS!”, it’s terrifically dark and funny, plus downright catchy with some wonderfully fat horns. The man’s voice is fabulous, too.
If you want to find any of his songs, you will want to search using the name Aurelio Voltaire. Apparently, there are other bands going by Voltaire these days. But to me, he’s the real deal.
