Today is McKinley Morganfield, better known as Muddy Waters', 100th birthday.

As a teen in Mississippi, Waters first began playing blues by blowing harp, but then learned to play guitar after he heard Son House and Robert Johnson. He eventually settled in Chicago in 1943. There he began playing regularly—running a juke joint, and making recordings of his own and as a sideman. In 1945, he was given his first electric guitar. By the early '50s, he had a regular combo and some blues hits, and at this point he was electrified—playing what was known as city, or urban blues. Those songs of his, the hits and misses (as well as his style) would become standard; a standard which would partially carry a culture, shifting weight, that still resonates today.
