Legendary composer, arranger, band leader and double bassist Israel “Cachao” Lopez (1918-2008) is universally recognized as one of the most prolific and influential figures in the history of Cuban Music. He was a co-founder of the widely popular mambo style in the late 1930’s (along with his brother Orestes “Macho” Lopez and Antonio Arcano), and a primary exponent of the “descarga” movement of the 1950’s. The album Jam Session with Feeling, presented here, was one in a series of recorded “descargas”, and includes several legends of Cuban music, such as Alejandro “El Negro” Vivar, and Tata Guines.
