Jack Black is a timeless classic. In nearly all of his major roles, he plays a raucous loser who overcomes his shortcomings and makes the world (or at least his own part of it) a better place. The irony is Jack Black himself appears to have very few shortcomings; he is great at what he does, and he knows it.

The surreal thing about the Tenacious D FFF Nites show at Mohawk was that nothing about Jack Black or his various roles and projects is cutting edge or reflective of high art. He is not doing this ironically. He is just a simple, funny man who likes to have a good time and likes everyone around him to be having a good time while he does it.

Regardless, the Fun Fun Fun crowd, including myself, enjoyed the show immensely.

The opening acts were, by and large, hilarious. Matt Bearden, local comedy superstar, was on point with irreverence and stories of double compound fractures while on LSD. The least impressive of the openers, Jenny Slate (Jean-Ralphio’s sister on “Parks and Recreation”), started off great, and I had high hopes for her. Then she began to discuss Sarah McLaughlin albums and beat “Space Jam” jokes into the ground. I gave her a shot, as “Space Jam” was my childhood, but she was far too drunk and not nearly stoned enough to pull off this crude attempt at ’90s ironic commentary.

Next up, and by far the most entertaining of the openers, was Craig Robinson, who played Darryl Philbin on “The Office.” He stole the opening with piano ballad parodies and superb audience interaction, and his delivery was sharp and practiced without feeling one bit forced; a true master.

The highlight of the night was, of course, The D. Jack Black and Kyle Gass have clearly been working together for years, and their onstage chemistry is both hilarious and impressive.

The set consisted of several songs from the movie “Tenacious D in The Pick of Destiny” (which, for the record, I find very funny), including “Dude (I Totally Miss You)” and “Kyle Quit the Band.” KG and JB ended with three Beatles covers, “Golden Slumbers,” “Carry That Weight” and “The End,” all blended into one. Their’s was a truly excellent live show and an interesting break from the more serious musicianship found at the main fest.
