this is where minimalism should have started,uncompromising and when you hear these orthodox works it makes all subsequent offerings, seem mediocre and self-serving, opportunist. You can check the various Minimalists Lists for Their Top Ten, and this piece is always in it if Not Numero Uno, Tony Conrad Terry Riley, Phil Glass as well, all Top Drawer Stuff;never argue with success but here I think you can, minimalism lives for the committment to its concept to its procedural dimensions, its working out of a place.Too bad the late Morton Feldman came to it quite late, and La Monte Young went into Eastern affinities,and his own indulgences.Well-Tuned Piano is Top Ten Stuff, Just Intonation great piece, It was a reaction at least in the visual arts artists as Richard Serra, Carl Andre, Robert Morris, Bridget Riley, Ken Noland, Bruce Nauman and Ellsworth Kelly, some go as far as saying that it was part of the Anti-War Times, against corporatism,but I don't think so for minimalism only works with a great deal of money and support buying old Army Bases as Donald Judd's in Marfa Texas, or Dan Flavin's flourescent lighting schemes,or Serra's massive plates, hundreds of thousands of dollars in steel mill productions; Art is Money. Here it is a wonder to hear this one organ chord transformations of organ registers, it makes you beleive again in art, what it was and may have become. You look at timbre as under a microscope, as we all think we do with other works. This one forces the issue a bit more.Charlemagne Palestine (Charles Martin), while he lived in Los Angeles area he had done a series of concerts in The Unitarian Church in Downtown LA, and this piece was part of those events. He has played this all over the globe, and it still holds a fascination as one of the primary works of American minimalism.
