Vintage NRPS is an album by the country rock group the New Riders of the Purple Sage.
[2][3] At the time of the Capitol Theatre shows, the New Riders of the Purple Sage were regularly performing as the opening act for the Grateful Dead.
Garcia would play pedal steel guitar with the New Riders, then play electric guitar and sing with the Dead.
A Grateful Dead concert from the same set of shows as Vintage NRPS was released as the album Three from the Vault.
All the songs were written by John Dawson, except "Honky Tonk Women" by Mick Jagger and Keith Richards.
