Two strums…two strums were all it took to make music history.

An electric pulse hits the listeners’ ears twice. Let’s hear it again:  Few people at the time had heard the sound recorded. The year was 1938, and when trombonist and guitarist Eddie Durham recorded his arrangement of “Moten Swing” with the Kansas City Five, it was one of the first jazz recordings made with instrument.

But that wasn’t the end of Durham’s progressive ways.; He also organized one of the first all-female orchestras. And he invented the “non-pressure” technique; a way of playing the trombone without too much pressure on the lips, as to not leave behind a mark after playing.
