When people hear this name, one thing usually comes to mind: guitars. And for good reason. "Before his attention was diverted toward recording multi-layered hits for the pop market, he made his name as a brilliant jazz guitarist" (CMT). Interestingly, he couldn't read music. What he did have was "a magnificent ear and innate sense of structure, conceiving complete arrangements entirely in his head before he set them down track by track on disc or tape" (CMT). Fast-forward to 1940, when Paul created his "innovative guitar, "The Log", built after-hours in the Epiphone guitar factory in 1940, was one of the first solid-body electric guitars" (Wiki).
"Paul also made several records with his Trio for Decca from 1944 to 1947, including jazz, country, and Hawaiian sides, and backed singers like Dick Haymes, Helen Forrest, and the Andrews Sisters" (CMT).
Les Paul died of pneumonia in 2009, but he left his mark as the father of American popular music forever.
