No, I don't think there is any music as intellectual as that. Even the most complex and dense music still has a sensuous texture that can be heard, even by those unable to aurally distinguish, say, retrograde inversions of tone rows. For examples of critically acclaimed music that pushes the limits of complexity, you might want to test yourself on some of the orchestral works of Boulez or Carter. Jim Tobin
