Any collection entitled 'Essential' 'Best of' etc opens up a minefield as admirers of a composer or performer's oeuvre is bound to say 'why didn't they include THIS instead of THAT?'.
And so it is here!
My main cavil is the lack of inclusion of one specific song from 'Songs From Liquid Days', Glass's collaboration with singer/songwriter lyricists, in favour of another, 'Changing Opinions'. 'Lightning' is very typical of 'vibrant, edged Philip Glass' and quite wonderful, but I'm surprised that he didn't include either the glorious 'Open The Kingdom', lyrics by David Byrne, beautifully sung by Douglas Perry, an example of a soaring melodic line arching over Glass's densely packed orchestral textures. Or, perhaps an even more surprising omission, given that his ability to write for the male operatic voice is much illustrated anyway in the various excerpts from Satyagraha, again with vocals by Perry, is the lack of either of the Linda Ronstadt numbers from Liquid Days - particularly 'Forgetting'. This was such a good combination of Glass's music with classical musicians (Kronos Quartet) and singers associated with more popular music - Ronstadt and The Roches.
Facades is a pretty essential essential really, and its wonderful to hear so much of Satyagraha and Perry and the shivery strange counter-tenor Akhnaten music - but there are an awful lot of other works by Glass out there, and it might have been good to have had tracks from more of the albums, rather than restrict it to several from a few.
There are also several tracks which give no indication of which CDs they originally come from (in fact, its only Satyagraha, Akhnaten and Einstein on the Beach which are acknowledged) So this is unhelpful to listeners who may be particularly taken by a particular track/period of Glass's compositions and want to delve more deeply into the CD the piece comes from.
4 rather than 5 star more for the failure of better sleeve notes and a slightly narrow selection criterion. The pieces themselves - well, wonderful.
