People either like this stuff or they don't. Usually I find it's too jazzy for some or too extreme for others. There's always the novelty factor though, the covers make interesting conversation pieces if you have a friend over browsing your album collection.
BlackBox is a double disc release by Avant that collects both the original Torture Garden and Leng Tch'e albums as original versions were hard to find because of their explicit artwork - ironically, BlackBox itself is hard to track down now too.
Torture Garden consists of 42 grindcore experiments or hardcore miniatures, if you like. Imagine a blend of Carl Stalling (scorer of Looney Tunes/Merrie Melodies cartoons) and Extreme Noise Terror.
The music of Leng Tch'e, performed by the same line-up is - in terms of tempo and arrangement - the opposite of Torture Garden. This album is a 30 minute dirge that is frequently described as doom metal and it's a fairly obvious go-to point because it prominently features heavily distorted, low-tuned guitars with lots of feedback, but then screaming. Lots and lots of screaming.
