New Riders of the Purple Sage is an American country rock band. The group emerged from the psychedelic rock scene in San Francisco, California in 1969, and its original lineup included several members of the Grateful Dead. Their best known song is "Panama Red". The band is sometimes referred to as the New Riders, or as NRPS. The roots of the New Riders can be traced back to the early 1960s folk/bohemian/beatnik scene in San Francisco, where future Grateful Dead guitarist Jerry Garcia, often played gigs with like-minded guitarist David Nelson. The young John Dawson, also known as "Marmaduke", from a well-to-do family centered in Millbrook, New York, also played some concerts with Garcia, Nelson, and their compatriots while visiting relatives on summer vacation. Enamored with the sounds of Bakersfield-style country music, Dawson would turn his older friends on to the work of Merle Haggard and Buck Owens while providing a vital link between the East Coast, Timothy Leary-dominated psychedelic scene and the West.
