Juan Gabriel was one of the most important figures in 20th-century Mexican music. He began writing and singing songs in Juarez but his reputation spread quickly. After signing to RCA, he became one of Latin music's biggest stars and wrote some of its most enduring songs, including "Querida," "Hasta Que Te Conoci," and "Amor Eterno." Gabriel was also a noted producer (Rocío Dúrcal, Lucha Villa, Lola Beltrán, Paul Anka). His tireless touring schedule -- with many concerts lasting more than four hours -- won him an international reputation. In 2015, he released an album of duets with three generations of top Latin artists. One year later, however, he died tragically of a heart attack while on a tour of the U.S.
