 The Guitar Trio continued touring in 1980 . De Lucía reportedly suffered from headaches and backaches while performing because he found it difficult to improvise and follow McLaughlin and Coryell 's advanced knowledge of jazz improvisation . Paco professed , " Some people assume that they were learning from me , but I can tell you it was me learning from them . I have never studied music , I am incapable of studying harmony — I don 't have the discipline , playing with McLaughlin and Di Meola was about learning these things . " In 1981 , Coryell was replaced with Di Meola , and The Guitar Trio released one of their most successful records , Friday Night in San Francisco , which sold over 1 million copies and generated a significant interest in flamenco music in America and Europe . It featured an extended combination of Mediterranean Sundance and Río Ancho ; this became arguably the piece most associated with the musicians . De Lucía also formed the Paco de Lucía Sextet in 1981 ( which included his brothers Ramón and Pepe ) , and released the first of its three albums that same year . On 30 August 1981 , de Lucía performed a solo set at St. Goarshausen in Germany , where he performed Monasterio de Sal and Montino among others and later performed with The Guitar Trio . The event was broadcast on national WDR television .
