This is a cliché statement and it’s not that black and white. He isn’t really a ‘performer’ — he has zero interest in theatrics, he has zero interest in stage banter, he has zero interest in connecting with the audience in the way that an actor or frontman is, and he’s got zero interest in pleasing casual fans with a greatest hits setlist. So if that’s what you’re into or looking for, then stay far far away.
But musically, he’s fucking awesome. And if you know the catalogue, he’s one of the few who’s really worth seeing over and over again. His band is amazingly tight. The songs evolve on a night-to-night basis in the kind of way that bands like the ‘great’ (or Grateful) jam bands never could. Structural improv vs wankery.
