In 1959, a family friend went to the home of Paco de Lucía and Pepe de Lucía where he made several recordings with a Grundig TK46 tape recorder. This tape disappeared in 1967 and, after a long search process, was rediscovered in 2022, when a restoration process started using AI tools. The historical value of this recording is incalculable, and it gathers in 21 pieces an anthology of flamenco where most of it's variants are represented (tangos, soleá, seguiriyas, bulerías...). It is, in short, the definitive recording to illustrate the transition from classical flamenco to modern flamenco as we know it today and the first know recordings of Pepe and Paco de Lucía.
