For this week’s edition of the All They Years Live video series, Grateful Dead HQ is looking back at the band’s June 9, 1991 stop at Ohio’s Buckeye Lake.

Previously, All the Years Live showcased the “Reuben and Cherise” from the Summer ’91 stop, but this week they’re looking at a set one-ending “Let It Grow” that stretched well over 12 minutes.

“One of the strongest, most inspired tours of the Dead’s final decade and a half of performing was the Summer Tour of 1991,” explains GD archivist/legacy manager David Lemieux. “With the two new keyboardists now fully ensconced in the Grateful Dead’s sound and repertoire, it was an unstoppable machine that hit the road for shows that summer. Countless A+ concerts were on this tour, at Deer Creek, Giants Stadium, RFK, Pine Knob, Soldier Field, and this mighty fine performance at Buckeye Lake in Ohio. Like ‘Bird Song,’ ‘Let It Grow’ was one of the longer, more jamming songs the Dead played in their first sets after 1976. Unlike the freeform improvisation of ‘Bird Song,’ though, Let It Grow was very structured and required precision focus by all seven players, and this one most certainly has that.”
