From the 12th to the 16th September, the metro station of Nuevos Ministerios will be putting on a flamenco show every single evening at 10 p.m. Among the guests who will be taking part are: Manuela Carrasco (flamenco dancer), El Lebrijano (flamenco singer), Antonio El Pipa (flamenco dancer), Falete (flamenco signer) and Tomatito (flamenco guitarist). Entry is free to these events but it would probably be advisable to get there quite early.
