Summer Tour 2018 Series: Part 1.  The first set featured is a strong example of the powerful second sets from the year it was performed.  It features an opening number not usually found in that slot, a great series of jams that follow it, and a muscular version of Walls of the Cave.  The second set featured has four Jam Chart tracks and the combination of musical factors we all hope to hear when a tour lands at the Gorge.
