There's a greater than zero chance that this is actually Czech grind's greatest achievement. Sleek, chromed off, heavily industrial in nature- it's at once a very natural musical idea and also one you never expected anyone to actually pursue. In a very weird, tricky space between The Berzerker, Agoraphobic Nosebleed, and particularly burly, militant skinhead hardcore, Four Seats For Invalides makes incredibly aggressive, violent, short songs with smashing drum machine (?) rhythms, ripping, modernized, hardcore-derived riffing, and a high/low vocal performance that comes across like a curbstomp. There's a very direct line from "Scum" to this. If you wanted to see a very stereotypical idea of "grind in the future," this is it, and I wish it actually was the future of grind.
Not sure whether to call this cybergrind or not, but I'll choose not to since that label tends to scare people off.
