This book includes biographical information on Carlos Prieto, his contributions to music, as well as a detailed catalog of 72 pieces commissioned and/or dedicated to him. A graduate of MIT and a former director of Fundidora, the biggest steel company in Mexico, Carlos Prieto decided at the age of 38 to abandon his career as a business man and become a full time professional cellist. Since then he has premiered over 90 pieces, most of them commissioned and/or dedicated to him by Latin-American composers. These commissions and dedications represent about 50 percent of the music written for the cello by Latin-American composers. This is the first time a study has been conducted on this body of music.
