D3 LENGTH: 947 words HEADLINE: JELLYFISH PLAYS '70S POP WITH '90S BACKBONE BYLINE: David Barton, Bee Pop Music Critic BODY: "Remember "The Partridge Family'?" Andy Sturmer of Jellyfish asked the crowd at Sunday night's concert at the Radisson Hotel. "They'd always finish an episode playing in a hotel. And I always wondered, "What kind of band plays a hotel?' " He paused before answering his own question: "We do!" Which is not to say that Bay Area quartet Jellyfish resembles the Partridge Family, a relic of the bubble-gum '70s that can only be seen in the '90s on Nick at Nite. But Sturmer's question raised another: What kind of band is Jellyfish? And another: How can a band seemingly obsessed with such '70s cultural ephemera as the Partridge Family and Peter Frampton (which is how Sturmer repeatedly introduced new Jellyfish guitarist Eric Dover) create music so wonderfully turned out? After all, aren't we repeatedly told that the '70s were a loss until rock got authentic with punk in 1977? Jellyfish rejects that critical formula, instead revelling in the music of the early '70s (and '60s) and filling its album covers and T-shirts with images of candied fruit, electric blue icing, multicolored breakfast cereals and evanescent bubbles. "There," they seem to be saying, "Just try taking this seriously." But in fact, they do take it seriously, and Sunday night's 80-minute concert was a wonderfully played and beautifully sung example of what Jellyfish does: post-modern bubble-gum rock that owes its musical fealty to the Beatles but which shows the lessons of the Who, the Ramones, the Beach Boys, Queen and many others. Led by Sturmer, who plays drums at a special kit that allows him to stand up and sing at the front of the stage, the band laid to rest any suspicions that it might be a sweet concoction without any musical merit. Instead, Sturmer and his songwriting partner Roger Manning, who plays guitar and keyboards, along with Dover and bassist Tim Smith, were a musical powerhouse. Possessed of a tremendous sense of dynamics (it pays to have a songwriting drummer) and having honed their four-part vocal harmonies to near-perfection, the band turned in some jaw-droppingly beautiful performances. From the Queen-inspired dynamics of "Joining a Fan Club" and the guitar interplay on a cover of Badfinger's "No Matter What" to vocal harmonies on "The Ghost At Number One" that would have pleased the Beach Boys' Brian Wilson, the group was exact in its re-creations of what were nearly all of the songs on its two albums, "Bellybutton" and "Spilt Milk." And while reproducing the intricacies of their two albums -- greatly helped by excellent sound -- they also performed with verve, turning what might have been a technically perfect recital into an energetic experience. It climaxed with the thunderous "A ll I Want Is Everything," with Lyle Workman (formerly of Sacramento's Bourgeois Tagg) guesting on lead guitar. Just as important, Sturmer proved to be a witty master of ceremonies, describing road food ("Remember when you were a kid and you'd say, "When I grow up, all I'm gonna eat is pizza'? Be careful what you wish for. . . ") and deftly handling a noisy Slayer fan in front of the stage. Alas, the market for Jellyfish's sly '70s retro pop may already be shrinking. Despite the pleasures of the albums and the group's skilled live performance, the band drew only a few hundred people, despite having sold out the 950-seat Crest on its last to ur. To be sure, Jellyfish doesn't create great rock 'n' roll -- the members are wise not to take themselves too seriously because they're not in the same league as the people from whom they've gotten their best stuff -- but Sunday they paid homage with passi on, skill and love, and delivered an evening of hummable fun.
