My growing collection of Phillip Glass's music is entirely instrumental, and I was unaware that much of this collection is from his modern opera work. As I'm not a huge fan of opera, I was a little taken aback as this began to play, but by track 2, 'Changing Opinions', I was hooked. This is a wonderful collection of what I would call 'modern operetta', in that the music is accessible almost immediately, it's very melodic (no screeching!), it's possible to make out the lyrics, and still recognisably by Glass. There are a number of instrumental pieces here, including the wonderful 'Facades' and 'Metamorphosis 4', but the opera extracts more than hold their own in this impressive company. A great collection, and an absolute 'steal' at this price. Not to be missed!
