There are lots of flamenco bars in the barrio Santa Cruz of Seville, but a good bet is to call in to El Tamboril in Plaza Santa Cruz about midnight. There's s a good chance flamenco singers and musicians will drop in and perform while you stand at the bar drinking your sherry (don't worry - it's a completely different drink to the maiden-aunt stuff that gets exported.)

Hotels will be able to fix you up with tickets to a tablao flamenco show - if you fancy watered-down drinks in a cabaret-style approximation of flamenco.

All I can tell you about Salamanca is that it's an impossibly beautiful medieval university town. We stayed in posibly the worst room we've ever had - in possbly the best location, with an iron balcony over the graceful collonanaded main square. On Sunday morning, after church, a few old guys with pipe, tabor, and other instruments began playing tunes, while people in their very chic Sunday best, returning from Mass, gathered in a circle, raising their arms and dancing whatever the local dance is there - a bit like the Sardana, in Barcelona. We'd no idea it was going to happen, and it's a great experience.

There's a lot more to Seville and Salamanca than just the music, though, and you'll have a great time. Sorry I can't help you with Santander.
