Music in late XX century needed a review. Things went too far from Stravinsky and Prokofiev to Stockhausen and Boulez, passing through Berg and Schönberg. All has been invented in the XX Century. What should be the new proposals?
Glass is one of the new composers. Too tight to New Age, he has been compared to Nyman and Mertens, because of the usage of a term: minimalism. And in this CD, Glass is really close to this concept, and far from his biggest operas.
Minimalism is repetition. One should consider this a joke, but it is a new concept. And like any other new proposal, it is of the greatest importance in the music of the second part of last century.
However, Glass could have made real variations of his Metemorphosis in order to be a little less minimalist. Number One and Number Five are almost the same. Number Four is my favourite.
In fact, Einstein on the Beach, Akhnaten and Satyagraha are more solid, but this album is a very good way to understand what can be classic and brand-new at the same time.
