Pedro Aznar, born in Buenos Aires, Argentina, studied classical guitar, piano, electric and acoustic bass, percussion, and composition in Buenos Aires and at the Berklee College of Music in Boston, MA. He founded the group Serú Girán in 1978, one of the most popular and influential ensembles in Latin American popular music. Serú Girán disbanded in 1982, but reunited in 1992, producing a platinum studio album and gathering the largest audience, to that date, for a concert tour in Argentina. Aznar joined the Pat Metheny Group in 1983 as multi-instrumentalist and singer after Pat Metheny heard a tape of his home recordings. The group featuring Aznar in the lineup toured the world extensively and recorded three Grammy-awarded albums: First Circle, Letter From Home, and The Road to You, as well as the soundtrack to the film The Falcon and the Snowman. Aznar's second solo album, Contemplación, featured the accompaniment of several members of the Pat Metheny Group. As a member of the Pat Metheny Group, Aznar played guitar, saxophone, both untuned and tuned percussion (including steel drums), and melodica, in addition to singing and whistling. He also wrote or co-wrote several songs included on Pat Metheny Group albums.
