Flamenco show in Barcelona

Without wishing to engage in polemic, flamenco is really not a Barcelona thing, rather an art form associated with the southern part of the country. This is similar to wishing to see good Dixieland Jazz in Wisconsin. While you might find a venue, it will probably be focused on tourists, and of dubious authenticity. That said, BCN is a city of 4 million inhabitants, and it is likely that there be a quality flamenco club someplace, but it'll take some work to find it. If nobody else replies with a recommendation, you might try asking in small record shops. Olé!

Gabriella, If you want to see Flamenco, you're better off heading to Madrid instead of Barcelona.
