Bill Monroe: Father of Bluegrass Music

Jerome John "Jerry" Garcia (August 1, 1942 – August 9, 1995) was an American musician best known for his lead guitar work, singing and songwriting with the band the Grateful Dead. Though he vehemently disavowed the role, Garcia was viewed by many as the leader or "spokesman" of the group. As one of its founders, Garcia performed with the Grateful Dead for their entire three-decade career (1965–1995). Garcia also founded and participated in a variety of side projects, including the Saunders-Garcia Band (with longtime friend Merl Saunders), Jerry Garcia Band, Old and in the Way, the Garcia/Grisman acoustic duo, Legion of Mary, and the New Riders of the Purple Sage (which Garcia co-founded with John Dawson and David Nelson).  He also released several solo albums, and contributed to a number of albums by other artists over the years as a session musician. He was well known by many for his distinctive guitar playing and was ranked 13th in Rolling Stone's "100 Greatest Guitarists of All Time" cover story. Later in life, Garcia was sometimes ill because of his unstable weight, and in 1986 went into a diabetic coma that nearly cost him his life. Although his overall health improved somewhat after that, he also struggled with heroin addiction,  and was staying in a California drug rehabilitation facility when he died of a heart  attack in August 1995.
