Meshuggah—The Violent Sleep of Reason
Haven't listened to the whole thing yet but it seems pretty good. If you dig Meshuggah's distinct brand of mechanistic, polyrhythmic metal you'll probably like this album. If you don't, you probably won't. It was recorded live in studio as a band instead of bit by meticulous bit like almost all their other albums though so it does have somewhat of a rougher edge than their other releases.
