I'm not a fan of the 'sound track' genre; I'm usually the first to criticise it, as music for those who aren't music fans. However; when the score is such a fundamental part of the production, its a different matter.
Phantom of the Opera has one of the most famous scores of all musicals. It is the second longest running West End production of all time; to Les Mis. Sung by the amazingly talented Michael Crawford and Sarah Brightman; this is a beautiful album from beginning to end, what's more, the tracks run together seamlessly.
This is an absolute must have for any Phantom fan. I picked it up for £15 when I was 11; it was 3 weeks worth of pocket money, but I never regretted the spend.
Don't tell me you're a phantom fan if you don't own this album.
