Well, that pretty much sums up why this band is labelled 'Experimental'. But I must add the scratches are added tastefully and not overdone so it merges with the riffs and does not stick out like a sore thumb. This is a compilation and the Dj was only for one album so don't expect scratches on every track.
As far as the BDM part goes, there's nothing ground breaking happening here. The riffs sound similar to say Devourement and Dying Fetus but they do pull off quite a few surprised by doing so. The vocals are quite strong and mainly grind influenced. Get this album if you'd like to hear something new that hasn't been done bad.
