The legendary composer, arranger, bandleader and double bassist Israel "Cachao" López (1918-2008) is generally regarded as one of the most productive and influential figures in the history of Cuban music.

He was a co-founder of the widespread mambo style in the late 1930s and a key representative of the "Descarga" movement of the 1950s. The album "Jam Session with Feeling" presented here was one of a series of recorded "Descargas" and features several legends of Cuban music, such as Alejandro "El Negro" Vivar and Tata Güines.
