these were the first known shows Garcia had played with NRPS since November '69
The Jerry Site does list shows on March 13 and March 14, while the NRPS concert history lists 2/7/70. I need to investigate those dates further.
Still, LIA's observation is one worth emphasizing: there is no known (to me!) NRPS activity during December 1969 or January 1970, and at most sporadic activity through March 1970.
I find this puzzling, so I'll pose the question: where were those guys and what were they doing? Did the GD's studio work crowd out or swallow up everyone's efforts? Were the GD working on their acoustic sets, leaving less time for Jerry to work on pedal steel (which is a variant of the same question)? Were the New Riders gigging without Jerry, but I have just failed to note it (entirely possible)? Something else?
I'd love to hear thoughts or to get some info on the whereabouts of Marmaduke and Nelson during this timeframe.
