Be prepared to read the same kind of reviews for super-guitarist Danny Gatton as those that haunted a similar figure the late, great Roy Buchanan, a legend of the guitar whose blues-rock career never got off the ground despite critical praise. Such flip dismissals as ''plays great, less filling'' missed the point with Buchanan, and these days with flashy technobores like Joe Satriani and Steve Vai charting regularly they're especially off the mark when applied to Gatton. Dubbed ''the world's greatest unknown guitarist'' by those who care about such things, the 45-year-old D.C. legend can play just about anything he wants, be it rockabilly, jazz, R&B, or straight rock & roll and does so regularly. 88 Elmira St., a major-label debut, features a scorching batch of instrumental originals and a few distinctive covers including the Beach Boys' ''In My Room'' and the theme music from The Simpsons all the while displaying the charm and sense of humor other frantic fret-boarders typically leave at home. You couldn't ask for a better party record: It's got fun, flash, and, best of all, feel. B+
