Philip Glass is a taste I have very gradually acquired. Having heard this distinctive music first incidentally featured in radio and television programmes, it has gradually seeped into my musical consciousness. The more I hear, the more skilful I realise it is, and this surprising CD has further enhanced my appreciation of it. I wouldn't have heard it had I not attended a Barbican concert on 12 January 2002, where this choir performed Glass's invigorating Itaipu; that led me to this CD. I find I have had to give time to Glass. The slowly changing harmonics under what at first hearing appears purely repetitive melody is curiously seductive and restful. It is not, I imaging, easy to perform; the Crouch End Festival Chorus is, like almost all large choruses, amateur, in that they are not paid. But the standards are most certainly professional, from the evidence of this (and the concert). And the recording is 'as live', which adds undoubted energy. Give it a try.
