is Maynard singing kargyraa?

While listening to the new Tool single, Vicarious, I did a double-take when I thought I heard a vocal technique I’ve only heard used by Tuvan throat singers.

“it’s no fun ’til someone dies”

The word dies sounds an octave lower than the note I’m always expecting him to hit.  It has a guttural timbre that reminds me of the kargyraa style of throat singing, where the ventricular folds (a set of “false” vocal cords above the main ones) produce an “undertone” that is one octave below the fundamental tone produced by the vocal cords.

Having only recently begun to understand the technique of kargyraa and practice it myself, this was a pretty cool thing to hear.
