This better makes its way back with vox!
The decline of notes at the tail of that fat open riff reminds me a lot of Megadeth, kick ass stuff! This really kicks you in the head, dude, most certainly a nice brutal sound, especially with the double bass you threw in! One thing I suggest though, is after you record your guitar tracks, take the drums out and replace them with a new track without the hi-hat counting down to the next riff (unless you can do that some other way), I just noticed you do it a lot, I think it might sound cool to hear everything hit you unexpectedly. Anyway, as always, I love your work!
