By the summer of 1990, the Grateful Dead were deep into one of the most bittersweet stretches of their long career. Brent Mydland had been the band's keyboardist since 1979, and his bluesy, full-throated presence had become absolutely central to how the Dead sounded in the arena era — his voice cutting through the mix on ballads and his organ churning underneath the jams with real emotional weight. What none of the fans at Cal Expo that June night could have known was that Brent had less than two months to live. He would be gone by late July, and that lends every show from this final run of his a quietly elegiac quality in retrospect. The band was also riding the commercial momentum of "Built to Last," their 1989 studio album, and the touring machine was running at full tilt through the early summer stadium and amphitheater circuit. Cal Expo — the California State Exposition grounds just outside Sacramento — was a reliable Dead stop, a large outdoor amphitheater that the band returned to regularly through the late '80s and into the '90s. Sacramento crowds had always been warm and partisan, and the open-air setting suited the band's sprawling improvisational style. There's a regional loyalty embedded in these shows; Northern California always felt like home turf, and the Dead tended to play with a certain ease and confidence in front of these audiences.
The songs we have from this night are a real cross-section of what made a 1990 Dead show worth the drive. "Crazy Fingers," that gorgeous, harmonically complex Garcia composition from "Blues for Allah," was a relative rarity in the rotation, and any appearance of it is worth your time — the chord voicings are unlike almost anything else in their catalog. "Eyes of the World" is one of the great vehicles for extended exploration, a song that can stretch from tender to transcendent depending on how the night is going. The pairing of "Playing in the Band" into "Space" suggests the band was in an adventurous mood, willing to push into the abstract. And the Brent-fronted "Wang Dang Doodle" is exactly the kind of second-set barn-burner that reminded you he wasn't just a sideman — he could anchor a room. "Standing on the Moon," meanwhile, is pure Garcia heartbreak, a song that only gets heavier knowing what was coming. If you're hearing this for the first time, pay attention to the space between the notes — the way Jerry and Bobby and Brent find each other in the quieter passages. This is the sound of a band that knew each other completely, and that knowing is all over this tape.
