I did manage to come across some interesting music, aside from the Vivaldi concert on the last night.

There was this oldish bloke busking with a guitar in a square - after singing a few songs in a beret, he changed his hat to a more florid affair, and sang in a completely different style. Neat idea.

But the mst intetresting was a Russian from Siberia busking with a set of musical glasses. Extraordinarily skilful, but tasteful as well, made some loively music. Ran into him on the first night walking around, and then wished we'd paid him more attention, but he wasn't there any more. And then we ran into him again towards the end of our stay, and this time we bought his CD, and it's amazing. Vladimir Sklyarov is the name.

This was the first time I'd run across them, but I gather the Musical Glasses have been around quite some time - Mozart worked with the instrument on occasion. And so did Benjamin Franklin. Here is a page about it.
