Someone talking about a '81 album reminds me

P2P networks have given me the opportunity to get listenable copies of most of my old vinyl LPs and, in some cases, see what else they've done.

I've all the Rick Wakeman albums from the early/mid 70s (Arthur is particularly good, even 27 years on) and wondered how many other's he's done.

Since 1981, Kraftwerk have released let's call it one and a half albums of new stuff.

Since 1981, he's done ninety.
