I'd been rather avoiding this Discworld novel because I feared it would be much the same as Moving Pictures and Maskerade, both of which are essentially one-joke books where the joke is stretched beyond its limits. But actually it's much better. For a start, a lot of jokes about rock music are actually funny, riffing lots of little laughs off the one big laugh. Also, the idea of Music With Rocks In fits into the Discworld milieu much more comfortably than either cinema or opera. And another story element is the relationship between Death and Susan, which gets rather similar plotting in other books but somehow seemed to work better here. Good to have caught up with this one at last.
