by Johnny Loftus Emerging from the ashes of hopeful 1990s Philadelphia alt-rock combos like Dandelion and Trip 66 is Laguardia, who issued its debut, Welcome to the Middle, through Universal/Republic after a false start with Interscope. The quartet's flair for the tightly wound, slightly ironic alternative pop song becomes almost immediately apparent with "Holy Ghost," which jitters and shakes with handclaps, stops, starts, and a vintage indie rock guitar line. However, from opener "Roseanna" through the dirgeful chording and squiggly keyboards of "Butterfly," it's Radiohead that casts its long, pasty white shadow down Laguardia's creative runway.
