Waldo De Los Rios

Waldo de los Ríos (7 September 1934 - 28 March 1977) was an Argentinian composer, conductor and arranger. He is best-remembered for his ability to transform European classical music into pop music. His 1971 arrangement of Mozart's Symphony No. 40 recorded with the Manuel de Falla orchestra, reached the top spot in the Dutch charts and scored a top 10 hit in several other European countries. In 1970, prior to this success, Waldo de los Rios had already climbed the charts around Europe and America with Ludwig van Beethoven's Ode To Joy which he arranged and conducted for Miguel Rios.
