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.
