These muicist met in the house-musical study El Cielito, 30 km far from Buenos Aires, to compose music together. Some other musicians also took part: from Spain Amaral and Pereza, and from Argentina (Bersuit, which was only for the welcome, Súper Ratones and Lisandro Aristimuño), but nevertheless the initial plan the only musicians really involved were the promoters of the lab. The project was a collaboration with SGAE.
