Guitarist, mandolinist, singer and songwriter, Lester Flatt, played in a number of bands during his 20s all throughout the American south. In 1945, he joined Bill Monroe and the Blue Grass Boys and the history of country music was altered forever. Flatt played rhythm guitar and sang lead vocals for the legendary group for 3 years, churning out dozens of hits that shaped the eponymous new genre: Bluegrass.
In 1948, Flatt left the Blue Grass Boys along with banjo player, Earl Scruggs. The two would team up to form Flatt and Scruggs and the Foggy Mountain Boys and become one of the most popular bluegrass acts of all time.
