They have a great sound and their riffs are industrial strength. I also quite like how irreverent they are and how the consistent they are with their cheap (literally, it doesn't cost much) gimmick of pointy hats. I first heard their song Ambrosius, which sounds like an epic battle of light and darkness but the mysterious lyrics (You can eat from the ground) turn out to just be a dude talking to his lazy cat. It's one of the clearest cases of music being at the forefront and it's total quality
