I always think of Crim's Discipline as the ultimate math rock record.  It 
sounds like the music can be defined by equations.  Like, if you plot 4x 
+x2y(y-z)/x-z, your solution will be whatever that is Fripp is playing. 
Also, I think of math rock as, you can imagine that the musicians have to be 
counting along in their heads to play the changes and changing time 
signatures.  Remarkable thing about Fripp: his.. lips... never... move.

I feel like, music and math are the languages of the universe.  Math rock is 
when you can see how music and math resemble one another.  However, math is 
probably the last thing you want in your head when grooving to some tunes 
(and that from a Crim fan.)
