The musical souls of two nations, Ireland and Mexico, are movingly brought to life in San Patricio, the latest international collaboration by six-time Grammy winners The Chieftains - the leading practitioners of Irish traditional music for the past four decades. The album features multi-instrumentalist, singer and composer Ry Cooder, another multiple-Grammy winner, who co-produced with The Chieftains' Paddy Moloney. It tells the nearly forgotten story of the brave San Patricio battalion - a downtrodden group of Irish immigrant conscripts who deserted the U.S. Army in 1846 to fight on the Mexican side against the invading Yankees in the Mexican-American War (1846-1848).
