"Keith turned into a fire-breathing demon about halfway through the fall [1971] tour—not only following the band effortlessly through all our endlessly bifurcating highways and byways, but grabbing the ball and running with it, leading us into unknown regions and setting the stage for what many heads consider the peak years of the Grateful Dead. With Keith, we became the turbocharged turn-on-a-dime Grateful Dead that had only been hinted at before, but the music also became warmer and more organic, almost but not quite filling the hole Pig's absence had left." - Phil Lesh, Searching for the Sound
