 This album is considered by many music critics and fans as one of the most important works of modern Spanish (Iberian) rock and a turning point for the music industry in Spain.Rios sold over 450,000 copies in less than one year, a feat he never again came close to surpassing.Ironically this concert was a celebration of his 20 years in the music business, yet most of the audience members had not even been born when he began his career.
