Forty years ago this week the Grateful Dead embarked upon a great tour of Europe. So great that they redefined themselves during it. The band was a mere eight years old, but they were playing like they had surpassed the cosmos in musical interactivity.

This month and next on A Season in Hell with John Hell, I’ll be playing some of my favorite tunes from this tour. That’s eight weeks of some supreme jams mixed in with some of the finest new music happening right now.
