I consider it is a very vast series, that has the music on its centre. You see how Spain during Franco's dictatorship was, how that influenced in the concert's rooms, on the radio with the censorship or with Eurovision contest... However, the richest is the relation between Robert-Maribel-Guillermo, that creates the opportunity to progress to others stories equally interesting, with others characters developed, has Zabala, Ángeles, Fanny, Maribel's family, etc.
It is curious to understand the differences between Maribel's and Robert's familiar context, or the interventions of the government, or the action of the music enterprises with Mr. Alfredo e Mr. Vidal.
Everything it is related with music, and the music is the centre of this narrative that shows how to follow your dreams, to love intensely, the importance of have really true friends, and never forget the love to rock and roll!
