The festival was born on 2015 and, in the first edition, it comprised two shows with full electric setup in Centre Cívic Can Déu and in New Underground, Barcelona, plus a special acoustic show in Centre Cívic Riera Blanca. A unique experience in the city to date, combining progressive rock and post rock with other influences and generes close to Jazz. The festival had a good response and it was mainly due to the good quality, reasonable price, nice environment and family-friendly time schedules. The festival would not only continue in the subsequent years, but would also grow until becoming one of the prog/post/jazz landmark events in the city.
