The song/riff in question is in the intro of a song by "After the Burial" called "Cursing Akhenaten".
I cut a full measure out of the intro and looped it. I uploaded it for anyone who wants to take a crack at the answer. Here's the link - Intro of Cursing Akhenaten
Also, there are tabs for the song located here but I can't say for sure that they are accurate.
Does anyone know what scale this is? On another, yet related, note, are there any sites that try to help identify scales provided tablature and tuning?
