I somehow missed this take on The Amadeus Net by the prolific reviewer, Donald D’Ammassa:
Satire used to be a lot more popular in SF than it is today, possibly because we’re all aware of the problems and don’t need to be nudged any more. This one – from a publisher of whom I haven’t previously heard – is actually quite a good one, with an interesting premise. Mozart was actually immortal, faked his death, and is still alive some twenty years from now, in a future where sex change clinics are an accepted part of life. There is a nice mix of plots including a possible apocalypse, a journalist who knows his secret, attempts to steal and sell his DNA, The author pokes fun at a variety of modern trends and foibles, and for the most part does so wittily and entertainingly.
