Query: Dense and rich. John Cage would be proud.

This new double CD set by Aphex Twin offers more of the kind of electronica one should expect from RDJ. However there is a much more dense and varied texture involved in many of the more intense pieces. What is surprising is the focus on piano in these albums. Many of these pieces on piano (both prepared and otherwise) sound like the melodic and harmonic tracks from the electronic pieces, without drums. There also seems to be a surprising lack of form to the piano pieces, whether you view that that as a plus or not ("jynweythek ylow" being the best piece). Overall, this set isn't Aphex at his apex, but I does create some speculation as to what he'll do with the piano in the future.
