This basement bar, going for some 20 years now, was Madrid's first dedicated exclusively to blues. Run by a Swiss-Spanish guy called Albert, who has a large collection of old records that won't disappoint, there are live acts featuring local bluesers from Tuesday to Thursday.
The musical programme here includes both international names and local artists like Fede Aguado. The live performances are of high quality. Jam sessions are also scheduled, during which you can enjoy a beer or a mojito.
