As I remember it, these are very good live takes on Opera De Reims. I suppose Attahk is a good album if you want a little more shorter-song-based tunes. Otherwise they tend to stretch it out and do very long compositions, like Kohntarkosz. Don't miss out on their new material though, they gotten really good over the last ten years. Like the 3CDbox Trilogie, I used to consider that essential.
