1983 would see their last performances. Among Miguel Rios and Luz Casal, they took part in the tour "Rock de una noche de verano". This was a long series of gigs all around Spain, featuring a set of lights and sound asets as they never had been seen before. The tour was organized by Miguel Ríos, and few years later it would be marked as a milestone in the Spanish rock history. At the end of the "Rock the una noche de verano" tour, in the fall of 1983, and when they were at their best and most successful moment, Leño members decided to split off.
