To catch these Phish you'll need 3-D glasses

Intricate jams, flying glow-sticks, pot smoke hanging in the air, totally unself-conscious dancing - plus comfortable chairs, unbeatable views and air conditioning. This is the kind of almost-live experience that a 3D jam-fest concert film would ideally provide, and "Phish 3D," opening nationwide on Friday, does a pretty decent job of creating it. Plus, as one audience member at Brooklyn's April 20 screening put it, "If you take off the 3-D glasses, you can see what Phish usually looks like to most people."

Filmed over three days in October 2009 at the band's Festival 8 in Indio, Calif., "Phish 3D" focuses on two evening shows and one daytime acoustic set. The film offers both field-wide shots and close-up, instrument-level views during Phish's performances of favorite songs such as "Tweezer," "Maze," "AC/DC Bag," "Mike's Song," and newer tracks off their 2009 album "Joy," including "Stealing Time from the Faulty Plan." The film also contains portions of the band's performance of the Rolling Stones' "Exile on Main St.," part of Phish's Halloween "musical costume" tradition of playing an entire album by another artist.

Not just a gimmick, the 3-D aspect does add value in terms of bringing the concert experience that much closer to the real thing - crowd-spanning shots from behind simulate the feeling of being part of the audience; balloons floated by the real-life crowd caused theater-goers to swat the air in front of them. At several points throughout the film, theater staff tossed real glow sticks into the seats as concert staff would do at a live Phish show. Audience members danced, applauded, sang along and even lit up a few (something theater managers should undoubtedly be prepared for).

The film's biggest flaw is the sound mix, which favors the high end of Trey Anastasio's guitar and Page McConnell's keyboards over Mike Gordon's bass and Jon Fishman's drums, an imbalance that detracts somewhat from Phish's famed improvised transitions. And longtime Phish purists might lament the film's reflection of Phish's move away from extended, jazz-inspired improvisation to more straight-ahead, rehearsed rock performance.

Still, by the time the film closed with Phish's energetic horn- and backup-vocalist-supported performance of "Suzy Greenberg," the theater crowd volume was loud and a number of people were out of their stadium seats and on their feet.
