Released in 2002 as Proper Box 48, 
Ritmo Caliente marks an exciting high point in this label's catalog and may be the largest anthology ever devoted to 
Machito's Afro-Cubans. By focusing on the Caribbean dance music delivered by this band in the early ‘40s, the first of four CDs provides important background for 
Machito's historic collaborations with early modern jazz heroes later in the decade. In tracing his progress through the years 1947-1951, Proper illustrates how (like 
Tito Puente) 
Machito chose a more progressive path at a time when 
Xavier Cugat, 
Desi Arnaz, and 
Edmundo Ros each modified his act for more lucrative appeal to mainstream pop audiences. While Pablo's 
Mucho Macho is still the best single-disc introduction to 
Machito, 
Ritmo Caliente is recommended for those who want to delve deeper and learn more about this remarkable individual and his consistently excellent ensemble. Born in 1912 as Frank Raul Grillo in Havana, 
Machito sang and handled maracas from an early age. He came to New York in 1937 and made his first records singing backup for vocalist 
Alfredito Valdez. In 1938, he and his sister Graciela sang with 
the Septeto Anacaona, and he recorded with el Quarteto Caney, el Conjunto Moderno, and la Orquesta Hatuey. After serving as lead singer with bands under the leadership of 
Nora Morales and 
Augusto Coen, 
Machito joined forces with 
Mario Bauza in 1939 to form their first Afro-Cuban band. 
Bauza, who married 
Machito's sister Estella, is a figure deserving of wider recognition. In his youth he played clarinet, bass clarinet, and oboe with the 
Havana Philharmonic. After moving to New York at the age of 19, he blew trumpet with orchestras under the direction of 
Noble Sissle, 
Chick Webb, 
Don Redman, and 
Cab Calloway. It was 
Bauza who talked 
Cab into hiring 
Dizzy Gillespie, who later named 
Bauza as a major influence, whereas 
Machito drew inspiration from 
Webb, 
Duke Ellington, and 
Count Basie.
