Just the disc to give to those people who remark inquisitively about the relationship of music and mathematics.
Johnson actually explains out front before and at times during each piece about the math being used, and at times how musicians and mathematicians differ in their views. Many charming and lovely minimalist pieces for voice and very well recorded piano with sometimes unintentionally droll humor. A very original piece (as in "why didn't I think of that?"). (See also his piece "Failing: A Very Difficult Piece for Solo Bass" in Bang on a Can Live, Vol. 1 in collections.) ~ "Blue" Gene Tyranny
