I like Black Sabbath. I don’t love Black Sabbath. But I’m a big fan of “Am I Going Insane?” Ozzy’s vocals are spot on and practically molded into the song. Fantastic job of implementing them.
For most of these songs, the whole idea is that they are well worth other artists doing as well. But I’m not sure anyone can do the vocals justice here. I’ve listened to the Midlake version of the song. I like it, but the vocals do not present the same punch.
