This is the second of four posts on this year's Jazz on the Mountain festival.

Mohonk this year wanted a show for kids. Families always have come for the weekend, but I was amazed by so many kids in the parlor on Saturday morning: 2-year-olds running everywhere with moms and dads in pursuit, 4-10-year-olds singing along with Amy Cervini.

She was (with a runner and a newborn of her own) charming, singing sweetly, telling the kids about jazz, getting the kids to play little tambourines, getting the kids (of all ages) to sing along.

Joe Locke became a JOTM favorite 5-6 years ago when he played vibes so electrifyingly that he got the first ever standing ovation on a Saturday afternoon.

He's been the most requested comeback artist ever since, and this year came back (again electrifyingly, again in the Saturday afternoon "Joe Locke slot") for duets with pianist Frank Kimbrough -- whose solo of "Gone with the Wind" was hauntingly surreal.

John Scofield enjoyed playing last year's JOTM so much that he was game to return.

He especially wanted to play with Anat Cohen, and just about everyone at the Mountain House joined in the Saturday evening "ScoJam" -- playing to the biggest crowd ever in the parlor and the balcony above.

I requested a guitar solo, and he played a melancholy country song of George Jones, "The Girl I Used to Know." I'd forgotten that I'd requested (in an e-mail months ago) that he play a duet with Matt, and they whipped up a wild "St Thomas."

What's most remarkable to me is that some of the best music every jazzfest just...happens. John called up Joe Locke and, together with the house band, they played an impromptu frenzied "Afro-Blue."

Even with a painful finger, Fred played with ecstatic abandon, as if (he said) channeling Jaki Byard. I've heard so much (often great) music through the years that I'm rarely surprised, but at Mohonk I'm always surprised, as I was when Sco and Scott Robinson (on tenor sax) played an exquisite duet of "Old Folks."

Sco called everyone out, including trumpeter Mike Rodriguez from the audience, for a finale of "C-Jam Blues." After everyone played the first line, John improvised a second line, and as everyone jumped in for solos, Anat created riffs for the band to jam along.

Many folks who've been to Mohonk year after year said to me that the "ScoJam" was the best concert ever at Mohonk.
