This 1933 performance of “Dinah” is a perfect example of how free and radical Louis Armstrong was. He grounds the time at the bridge, flies over the A sections, and sings exactly the way he plays: Every choice he makes is undeniable, feels casual, and is extremely attractive. There is so much life and happiness in his singing and his sound. There’s wisdom and playfulness at the same time. He gives us the lyrics and then takes them away as he sees fit; it’s almost like an erasure poem. It’s a party.
