This is the fourth edition of a festival that has become unmissable for lovers of seriously hard rock. It takes place from June 30 to July 2 in the Parc de Can Zam in Santa Coloma de Gramenet, one of Barcelona's closest neighbours and reachable by metro. The festival features three days full of sharp, heavy guitar sounds with headliners Aerosmith back in Catalonia seven years after their last visit, as part of their 'Aero-Vederci Baby' tour, a farewell event after 45 years together, over 100 million records sold and countless awards. Also visiting Can Zam will be the legendary Alice Cooper, king of shock-rock, and the British icons Deep Purple, who have a new record out, 'Infinite' (2017). The line-up also features, among numerous other acts, local groups Rosendo and Soziedad Alkoholika, and metal bands Sepultura, Europe, Alter Bridge, Avantasia, Carcass, Sodom, Emperor and Abbath.
