On Friday, March 7th Jaime Gonzalo will be in Granada to talk about his new book "La ciudad secreta", at the Bakakai bookshop from 19:30 hours. "La ciudad secreta" represents a wide survey of Barcelona's experimental underground during the 70s and 80s. It's a choral portrait where many of its protagonists are interviewed, and it sets out to restore the identity and importance of a stimulating period which, in musical terms, can be compared to Germany's krautrock, England's Canterbury Sound or the French avant-rock scene, and which created its own live circuit, closely connected to the fanzine and cassette culture and independent radio stations.
