Born in Bilbao (Spain), he started studying music at the age of seven under the direction of his father, who at that time was the First Violinist of that city´s Symphony Orchestra. Later on he attended the Juan Crisóstomo Arriaga Conservatory in Bilbao, studying piano, composition and flute.

He graduated in Orchestral Conducting with maestro Octav Calleya and perfected his studies with maestros Enrique García Asensio, Antoni Ros Marbá  and  Sergiu Comissiona.

Amigo´s carrer as conductor started with the lead of the Madrid Real Conservatorio de Musica´s Symphony Orchestra ( 1995-1999 ) and that centre´s Grupo de Música Contemporánea. With these groups he worked extensively as a teacher and as a concert artist. His performances in the Auditorio Nacional de Música and the Musikfestpiele Saar ( 1999 ) received great compliments from the critics. In 2000 he was nominated Leading Director of the Extremadura Symphony Orchestra; in only five years they have swept the public and critics off their feet with their high-quality performances as well as their ambitious and attractive program.

His exceptional reputation secured by his musical integrity, his intensity and expressiveness have enabled him to present himself as guest conductor in Europe as well as in America and Asia. There he conducted orchestras of great repute, namely the Spanish Nacional Orchestra, the Reina Sofia Chamber Orchestra, the Bilbao Symphony Orchestra, the Madrid Community Orchestra, the Mexico State Symphony Orchestra ,the North Czech Philharmonic, Kammerorchester Berlin, Sinfonica di Roma,   Beijing Symphony,etc. He collaborated with great artists such as Joaquín Achúcarro, Maria Joao Pires, Teresa Berganza, Radovan Vlatkovic, Gerard Caussé,etc.

His repertoire includes all styles and periods, from Baroque to contemporary music, giving special attention to Spanish music.

Besides this, maestro Amigo is deeply involved in musical creation, an activity that has taken him to premiere and commission numerous works, and invest in the least played Twentieth Century repertoire , as is the case of his last Cd, nominated for a Juno Award, with works by portuguese composers Freitas Branco and Joly Braga Santos.
