intervals and harmony as gestures, not their regular use. meshuggah organic shadows maj7, how they utilize intervals in a gestural sense
how did they manage to utilize yet thwart the function of the maj7....so good. and the low min3 interval doesn't feel like a min3.
it could be that at different pitches/octaves intervals have different functions.
a unison 8th does not sound good layered on top of a maj7 (actually in this case the intervals themselves change the function of other intervals)
a cooler example:
a b9 with a high tiessiturs sounds amazing above a maj7 // lydian harmonic foundation. especially in a great moving context such as the solaris progression. (so additionally with this case a moving structure affects interval function).
austin rockman taught me this.
