When stars collide, sparks will fly. At least that’s the theory. Louis Armstrong and Duke Ellington accepted the invitation to record together with dignity and polite courtesy. While keen to see what this pairing might produce artistically speaking, it was certainly an historic occasion. As the red light went on and the tapes rolled, Duke on piano and Louis on trumpet and vocals, backed by the Armstrong All-Stars began to play. As Ellington hits the keys on a riff that sounds suspiciously like C Jam Blues and Satchmo sings cheerfully ‘Baby, take me down to Duke’s Place!’ the champions are ready to exchange ideas rather than blows. Perhaps unsurprisingly Louis soon emerged from this unique musical gathering as the natural born leader. But all the source material was firmly Ellingtonian. Both men had enjoyed extraordinary careers and were world renowned figures when the idea of bringing them together was first proposed.
