Furthur was an American rock band founded in 2009 by former Grateful Dead members Bob Weir and Phil Lesh. The original lineup also included John Kadlecik of Dark Star Orchestra on lead guitar, RatDog's Jeff Chimenti on keyboards and Jay Lane on percussion, and Joe Russo of the Benevento/Russo Duo on drums. Named after the famous touring bus used by Ken Kesey and the Merry Pranksters in the 1960s, Furthur was an improvisational jam band that performed music primarily from the extensive Grateful Dead songbook, as well as their own original music and that of several other well-known artists. In addition to the original members, the band's lineup included backup vocalists Sunshine Becker of the a cappella ensemble SoVoSó and Jeff Pehrson of the folk rock bands Box Set and the Fall Risk. After five years, Furthur disbanded in late 2014.

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".
