and his brothers recorded Interpreta a Manuel de Falla, a classical effort of compositions by Manuel de Falla. In 1979, de Lucía, John McLaughlin, and Larry Coryell formed The Guitar Trio and together made a tour of Europe and released a video recorded at London's Royal Albert Hall entitled Meeting of the Spirits. Pohren said that de Lucía's decision to work with musicians like McLaughlin, Di Meola, Coryell, and Chick Corea must have been an "exciting and stimulating" experience for him, given their technical musical knowledge and ability to improvise and said that they carried him "so far afield that at times he must have been profoundly confused, a man running the risk of losing his musical identity." This concerned de Lucía, who said in a late 1990s interview, "I have never lost the roots in my music, because I would lose myself. What I have tried to do is have a hand holding onto tradition and the other scratching, digging in other places, trying to find new things I can bring into flamenco." 1980s The Guitar Trio continued touring in 1980, with Larry Coryell being replaced by Al Di Meola in 1981. 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." Also in 1981, 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. In 1982, de Lucía put on
