Here is a link to the review of Angels in America in Opera Today.
Angels in America, Peter Eötvös’s opera based on the Tony Kushner plays, received its London premiere at the Barbican Hall. This was very high profile. David Robertson conducted the BBC Symphony Orchestra in a performance that will be broadcast internationally, online on www.bbc.co.uk/radio3..............Ultimately, Angels in America works on stage because the subject is so powerful. It packs such an emotional punch that it would be hard not to be moved by the human drama in the first part. A lot of choices had to be made when Eötvös and his librettist reduced Kushner’s seven hour saga. That’s all the more reason why decisions had to be taken for maximum dramatic and musical effect. As an opera, Angels in America might have served the subject better had it been less dependent on replicating the play, and taken a more original vision."
