Not the most exciting book to read (due to my non-academic practices) but very much an essential book on the composers Le Monte Young, Terry Riley, Steve Reich, and Philip Glass - the so called Minimalists. The beauty of the book is that the author Keith Potter pretty much focuses on the early works of these composers - which were minimal in nature. The thing is I feel minimalist music is really a huge canvas, and I'm hearing a lot of things in that context. For me, the most interesting chapters are on Young and Riley, because I know very little of their music - and even today, it is hard to find Young's music via the Internet. There are places, but nothing compared to Reich and Glass, who are everywhere. Riley I was surprised to hear his early music. Via ITunes, I downloaded some of his very early music - and i love it. Especially the music he made with Chet Baker. The technique is very much like the works of Brian Eno, in the context of Roxy Music or the albums he made with Robert Fripp. Riley was there first, and the music he made in the early 60's are as refreshing to the ear, as if experiencing the first days of summer after a cold spring. Riley had a recording deal with Columbia Records, so his music in the late 70's were known, but not the early works.
So, yeah, this book made me spend some great hours digging for the music from these exceptional 20th century composers. Excellent for reference, and each composer gets a good biography sketch. It is academic orientated, but that is what it is - still readable for the nerd (me) fan.
