Q: How many jam bands does it take to screw in a light bulb?

A: Only one, but it takes them three hours.

"Heck, I've got all day up here."

Heck, I've got all day up here.

And for the crowd at Field of Heaven to see Moe on Sunday night, that may not have even been long enough. Moe, the third-generation (at least) jam band from upstate New York ruled the clearing from 8pm to just after 11pm, including a 20-minute encore. They were playing with the current five man lineup of Rob Derhak (bass, vocals), Al Schnier (guitar), Chuck Garvey (guitar), Vinnie Amico (drums), and Jim Loughlin (more drums). The vibe went from Grateful Dead-style space to Southern Rock guitar heroics and even to the weird slapping riffs of Les Claypool-style bass.

Band leader Derhak wore a fishing cap and stood at the front stage in a laid back, I’ve-got-all-the-time-in-the-world posture, even when they were jamming hard. And at times he did have all the time in the world, like during the two consecutive drum solos, when he Schnier and Garvey all disappeared for a while offstage. They were probably having a beer, and during the break between the “end of the set” and the encore, they certainly were. Derhak came back with a can of Sapporo.

“It’s good to be back!” he said, and then in reference to the accumulating drizzle, “Bring the rain! Who cares? Well, anyway, I’m not camping.”

As if catching the gaffe, Derhak regained a tone of sincerity, and I can well believe he was genuinely grateful, because the audience really had been terrific. “You guys look good,” he told the crowd. “After all of this, after all of the weekend, you still look good.” And then Moe jammed out some more.
