I found them through a backward link from this review of Buika's CD, Mi Niña Lola, in which Daniel Brown quotes my comments on her concert in Salamanca. I don't think I'd yet appreciated what a still-too-rare treat I'd had hearing her live.
By the way, Buika is playing November 28 at the Palau de Música (wow! what a venue!) in Barcelona as part of the Barcelona International Jazz Festival. I'll be heading back from the States then, but if you're in Barcelona, I can't imagine a better treat than hearing Buika in the Palau de Música.
