Rock in Rio Music festivals are festivals whose main attraction is music. They normally take place in public spaces, with diverse activities of entertainment. “Rock in Rio” is a good example. It has already had some editions. This event is considered the biggest music festival in the world. It takes place in Brazil, Portugal and Spain. There are many reasons for Rock in Rio be the best festival in the world. It called my attention, mainly, because there are several artists, the entertaining activities and because it is for every age. Rock in Rio is the festival that called my attention for all the things I referred. Marta Barão
