Friday May 17 8:16 AM EDT REVIEW/MUSIC: Elvis Costello In Jovial Form Elvis Costello (Troubadour; 350 capacity; $20) By Phil Gallo HOLLYWOOD (Variety) - Smart move by Elvis Costello to introduce the intimate songs of his new album ``All This Useless Beauty'' in intimate settings such as the Troubadour. From a marketing standpoint, Costello gets to take these songs -- all of which were written for other artists -- to his core audience and industry players with the simple backing of his acoustic guitar and Steve Nieve's opulent pianistics. Everyone's left with the feeling Elvis -- now a jovial and smiling performer -- has been revitalized. The Troubadour show was part of an eight-day promotional campaign that included an appearance on ``Late Night'' (in San Francisco), several radio performances, a lunchtime gig Monday for executives at his Warner Bros. label and a show at the John Anson Ford Theater. While it should grease the wheels for the summer tour with the Attractions that will stop at the Universal Amphitheater, increased returns at retail remain in doubt. Costello's acoustic program -- more than two hours long -- played up adulthood and reflection, sliding in the old faves (``Alison,'' ``Angels Want to Wear My Red Shoes,'' ``Accidents Will Happen'' and ``Watching the Detectives'') to keep interest piqued with steel-sharp intensity. His voice rested and assured, Costello pumped the evening with vigor, humor and a pile of wordy songs that bordered on a Brechtian revue. The songs of ``Useless Beauty'' have far greater commercial appeal than those from Costello's last outing, the spotty ``Brutal Youth.'' Greatest revelation Tuesday was the introduction of ``Give Me Strength,'' a number composed with Burt Bacharach for Allison Anders' Brill Building fable, ``Grace of My Heart.'' The song is a pure throwback to Bacharach's great '60s work with Hal David, starting with a simple and drifting melody before climbing an emotional mountain that Costello's voice reached with strength to spare. From the new disc, Costello supplied a stunning one-two punch with the title track and ``It's Time,'' a pair of tunes that deserve a shortcut to familiarity and a prominent place in one of rock's greatest canons of the last 20 years.
