I believe I've heard these guys before, but the kid who was playing them for me was playing nothing but garbage quasi-brutal nu-metal. One of those 8 or 9 CD's was Mastadon, but the way you describe them had me thinking I should probably remember which band was Mastadon. But I can't, because it sounded just like the rest of that crap.
The review never states what kind of vocals the band uses. In fact, the review doesn't even decsribe how this music sounds at ALL. The genre is perhaps the most basic of all - Heavy Metal. How about a little more information on what I'm about to get myself into next time, eh?
Despite the big yellow caution tape clearly shelfing this album in the possible "risk severe ear bleeding" category (along with the frighteningly bad and over-hyped Slipknot Vol. 3) I will go ahead and find myself a sample or two.
