Trying to describe this French duo as 'math rock' would almost detract from how completely unique they are. They dance the fine line between what sounds like free improvisation and meticulously crafted structure. It's amazing how at one moment you'll be listening to something as if they're just going berserk on their respective instruments only to realize that they're suddenly stopping and starting on time with each other in a precise manner. With all of the blistering fretwork and free jazz drum stylings on these records, you can't really go wrong. Well, besides the fact that the only version of the second album I could find has some sound quality issues but other than that, it's truly magnificent.
