By the summer of 1990, the Grateful Dead were operating at full tilt as one of the most powerful live draws in American music — and also navigating one of the most bittersweet stretches of their career. Brent Mydland, whose soulful voice and muscular keyboards had anchored the band's sound through the '80s, had died just four days before this show, on July 17th. The band would press on, eventually bringing in Vince Welnick and Bruce Hornsby to fill the enormous hole Brent left behind, but in late July of 1990 the wound was still raw. Any show from this immediate period carries that weight. The band was grieving publicly, in real time, doing what they had always done — playing their way through the hard stuff. The World Music Theater, a large outdoor amphitheater in the south Chicago suburbs near Tinley Park, Illinois, was a relatively new shed at this point, opened in 1990 as part of the wave of purpose-built summer sheds that came to define the Dead's touring landscape in the arena era. It wasn't a storied room with years of mythology attached — no Cornell '77 magic, no Winterland ghosts — but it was a serious venue capable of holding a massive crowd, and the Dead played it repeatedly through the early '90s. Midwest Dead fans knew how to bring the energy, and outdoor summer shows in this era often had a loose, celebratory atmosphere even when the circumstances were heavy.
The songs represented in the database here give us a few good handholds. "Greatest Story Ever Told" is a perennial crowd-pleaser, a rollicking Bob Weir number built on a Bo Diddley beat that tends to come out early in the set with a kind of brash confidence — when it locks in, it's impossible to resist. "Playing in the Band" is one of the all-time vehicles for extended Dead improvisation, a song capable of opening up into vast, uncharted territory when the band is feeling it. As a frame for jamming it has few equals in their catalog. And of course "Drums" marks the center of the second set, that ritual passage into pure rhythm and space that separates the two halves of the night. What you're listening for in a show like this is the emotional undercurrent — how the band plays when they're carrying something. The recording quality for this date is worth exploring, as late-period shows often circulate in decent audience or matrix form from this era. Put it on and pay attention to the spaces between the notes.
