I sang a little while and then flew on.

So I was at this show (as well as the next two), and was deeply disappointed to have missed the Branford show preceding it. Nevertheless, I thought all 3 of these shows were solid with exquisite high moments. I must've been high because after listening to this show recently I completely missed the Dark Star teases between the I Want To Tell You tease and the start of Sugar Mags. More importantly, there is a distinct Spanish jam flavor at the 4 minute mark of Space. I do not remember this in real time at all, and it is not listed on any of these setlists including in Deadbase. Anyone else hear it?

IMHO, this is one of the weakest 1st sets of the Hornsby era. Jerry sounds like the last place he wants to be is standing on that stage. He is almost non-existent through large portions of the show (listen to the beginning of Let it Grow). It sounds like he is just rolling through the motions.
Second Set: shows signs of significant improvement in terms of energy with the Foolish Heart being the pre-drums highlight. Terrapin is very well played as well, with much more emotion on Garcia's part. Set II's backstretch is more typical of the high energy this septet was capable of.

I enjoy these '91 boards, good mix and good runs.

But don't let that fool you. 9/10 was head and shoulders above the first 2 shows of this run, and gave birth to 9/12 - 14/91, 3 very high energy shows with creative setlists and tight, inspired jams. This one, my only birthday show in 35 or so with the Dead, was amongst my all time favorites. The first set was fun, bu it's the Sugar Mag>Sunshine Daydream Sandwich that you need. Great song selection and execution both throughout the set - which is also notable for the Terrapin Station that made it onto the So Many Roads box set sandwiched into Playin, a nice Wheel, Black Peter and the Box of Rain encore. This show is among my favorites.
