Roots of Jerry Miller

H. P. Lovecraft was an American psychedelic rock band, formed in Chicago in 1967. Named after the horror writer H. P. Lovecraft, much of the band's music was inspired by the author's works. Their music combined elements of psychedelia and folk rock.

The Grateful Dead was an American rock band formed in Palo Alto, California, in 1965. Known for their eclectic style that fused elements of rock, blues, jazz, folk, country, bluegrass, rock and roll, gospel, reggae, and world music with psychedelia, the band is famous for improvisation during their live performances, and for their devoted fan base, known as "Deadheads". According to the musician and writer Lenny Kaye, the music of the Grateful Dead "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, the Grateful Dead are considered "the pioneering godfathers of the jam band world".

Riley B. King, known professionally as B. B. King, was an American blues guitarist, singer, songwriter, and record producer. He introduced a sophisticated style of soloing based on fluid string bending, shimmering vibrato, and staccato picking that influenced many later electric guitar blues players. AllMusic recognized King as "the single most important electric guitarist of the last half of the 20th century".
