We all owe to the eternal romantic Lester Young for the fact that the music on the “Cool Jazz” online radio station today can delight us with its broadcasting. Back in the 30s, he decided to “cool down” the usual explosive jazz tempo and add an improvised light note of slowness with echoes of a dry playing that was unusual for that time. It was the manner of emotional “coolness” and even a certain detachment that gave the musical trend the unusual name Cool Jazz.
