Grateful Dead was an American rock band formed in 1965 in Palo Alto, California. The band is known for its eclectic style, which fused elements of rock, blues, jazz, folk, country, bluegrass, rock and roll, gospel, reggae, and world music with psychedelia, the improvisation of their live performances, and its devoted fan base, known as "Deadheads". According to the musician and writer Lenny Kaye, the band's music "touches on ground that most other groups don't even know exists." For the range of their influences and the structure of their live performances, Grateful Dead are considered "the pioneering godfathers of the jam band world".

Bluegrass music is a genre of American roots music that developed in the 1940s in the Appalachian region of the United States. The genre derives its name from the band Bill Monroe and the Blue Grass Boys. Like mainstream country music, it largely developed out of old-time string music, though in contrast, it is traditionally played exclusively on acoustic instruments and also has roots in traditional English, Scottish and Irish ballads and dance tunes, as well as in blues and jazz. It was further developed by musicians who played with Monroe, including 5-string banjo player Earl Scruggs and guitarist Lester Flatt. Monroe characterized the genre as "Scottish bagpipes and ole-time fiddlin'. It's a part of Methodist, Holiness and Baptist traditions. It's blues and jazz, and it has a high lonesome sound."
