Keller Williams is usually put in the category of "jam band," even though for the better part of his career he has performed alone, creating tape loops to accompany himself. The exceptions to this lonely journey include his albums Grass, a bluegrass collaboration with the Keels, and Dream, which features a raft of guest musicians. But Live is really the first true jam band effort from Williams in the sense that it actually is performed by a jam band, here credited as "Keller Williams with Moseley, Droll & Sipe." That's bassist Keith Moseley, guitarist Gibb Droll, and drummer Jeff Sipe, and this quartet is very much a jam band and very much in the tradition of jam band progenitor the Grateful Dead. That comes across on this album not only in the music, but also in the sprawling length: containing two CDs, each running more than an hour, plus a 90-minute DVD that doesn't overlap with any of the material on the CDs, this package runs more than three-and-a-half hours. Then, too, there are the visuals on the DVD, which is a professional, if rudimentary effort in video terms, taken directly from the feed used on a screen shown to patrons of the shows. There seem to be only a couple of cameras in use, and they tend to stay fixed on particular simple shots of the players, although psychedelic special visual effects, rather like the geometric patterns available on the average computer CD player, break things up. It's like a modern-day version of an old San Francisco light show. On the CDs and the DVD, the band plays extended songs with long, meandering solo passages. Now and then, Williams comes to the microphone to sing, rap, or indulge in vocalese, presenting his whimsical novelty lyrics in a croon reminiscent of Michael Franks. Occasionally, the music veers into '20s jazz ("Reinhardt Rag") or heavy metal passages, but for the most part the styles will sound very familiar to Deadheads, a mixture of country-rock and exploratory electric instrumental music. In case anyone might miss the point, Williams even throws in his version of the Dead's "The Other One" and "Don't Let Go," a regular part of the Jerry Garcia Band's repertoire. Williams is an engaging, pixie-like presence on this disc, especially the DVD portion, but that doesn't keep him from playing well and proving himself an able bandleader after so many years alone.
