Concert line LENGTH: 1064 words HEADLINE: A Beatles reunion for Karl Wallinger and Jellyfish BYLINE: By Chris Heim BODY: If Karl Wallinger of World Party or the members of the band Jellyfish ever have a near-death experience of the kind depicted in the film "Flatliners," the first thing they will probably see on the other side is the smiling spirit of John Lennon. Beatles-esque pop has enjoyed continual revivals over the years. It has been a perennial favorite among Midwestern bands and such artists as Nick Lowe, Tom Petty, Dwight Twilley and the dBs, to name a few. Today, Wallinger (who, with occasional guest con tributors, constitutes the "band" World Party) is one of its finest exponents, and newcomers Jellyfish are adding a few interesting twists of their own. These days, psychedelic pop and Lennon's sardonic postmodern sensibilities, rather than the simpler, sweeter sentiments of early British Invasion, are the prime influences. That comes naturally for Wallinger, a Welsh lad who spent some time in the Waterb oys before striking out on his own with "Private Revolution" and his recently released second album, "Goodbye Jumbo." As a kid, he was obsessed with "Sgt. Pepper" along with a kaleidoscope of other '60s musical happenings, including Dylanesque folk-rock, that lean, driven "Beggars Banquet"-era Stones sound, and some Sly-style funk. Wallinger doesn't just patch all this together into some ugly Frankenstein-monster music. Elegantly eclectic and a studio perfectionist (like another '60s icon, the Beach Boys' Brian Wilson), he meticulously melds his influences into a coherent new sound and then fires it up with the primal e nergy that is the heart and soul of all great pop. And if Wallinger isn't exactly singing "Blowing in the Wind" or "Give Peace a Chance," he has inherited from Lennon and Dylan a strong sense of social responsibility and an uneasy suspicion that all is not right with the planet. Say you want a revolution ? Well, we'd all love to change the world. Wallinger at least is making it a bit more interesting. Jellyfish uses '60s influences more as a fashion statement than as a basis for an artistic manifesto. You might say the group plays Badfinger to Wallinger's Beatles. But it does have that '60s pop sound and spunky iconoclasm down fairly well on its recen t debut, "Bellybutton." Jellyfish opens for World Party (Wallinger and his touring band) Wednesday at the Vic.
