Decay - What´s E...?

Majestic progressive brilliance of a death metal band...basically everything I love about death metal and metal in general wrapped into one nice little Czech package. Imagine Therion and Xysma all melted down to their core elements and reassembled in an old eastern bloc factory...Decay indeed. How is it that I have not heard of this band before?! Much like that Supuration post from a while back, this one is turning heads and blowing minds.
