There was just one problem. Even the day’s leading edge of amplification technology carried bands only to a point, before the mixes muddled. Put frankly, Garcia or Jimi Hendrix live, at their loudest, sounded chaotic—in a not-so-good way. Today, defenders of How Things Sounded in 1969 must face critics who argue that everything back then sounded unsound on account of these gear constraints. That’s not necessarily to question the pure, unbridled daring of baby boomer bands like the Dead, at least not in their prime. The point is that amp tech just wasn’t keeping up with their sonic ambitions.
