I just finished an interview regarding New Orleans Jazz greats and thought you might find it of interest. They asked who my all-time favorites were; I replied that the Humphrey Band who performed at Preservation Hall.
That said, I thought there were two individual musicians, as opposed to their band, that stood the tallest among their peers. One of them, George Lewis who I knew very well and who performed Burgundy Street Blues and the other Sidney Bechet who played La Petite Fleur who I did not know. George played the clarinet and Bechet the soprano sax.
