Artist Biography Available in: The Mondragón Orchestra is a Spanish musical group created in 1976 in San Sebastián, around the personality of the singer Javier Gurruchaga, considered one of the pioneering musical groups in the fusion of music and theater in Spain. The band was based in its beginnings on two great scenic pillars: the singer, Javier, funny and eccentric, and Popotxo Ayestarán, a comedian who, using only mimicry, turned each song into a small gag humorist .
