Okay, this is awesome. Head Hits Concrete are a political grindcore band from Winnipeg, Canada. As some dude on the intertubes put it, they sound "like early Iron Lung, only out of tune". Just to clarify, out of tune = awesome in this case because holy fucking dissonance is this shit great.
I ended up buying this record from here (digital download only) and in all honesty, you should too. There's a lack of political/conscious grindcore right now and these guys need your support. The only reason I'm putting up a download link is because 1. it's not the whole thing (missing a good 10 or so tracks) and 2. more people need to hear this shit. I don't know about y'all, but I was pretty surprised to see that this band is hardly ever mentioned.
Just a quick breakdown of what I'm giving you here: 48 tracks of pure dissonant, aural assault and album artwork/booklet + liner notes/lyrics (just to put this record into context). Enjoy!
