Before they appeared on Saturday Night Live and The O.C. and were lionized by damn near every music scribe in the free world, the Killers were just another out-of-town act performing at the Larimer Lounge on a Tuesday night. Although the Lounge was only a quarter full -- the band was still flying well beneath the radar, and most folks opted to catch the Strokes at the Fillmore that night -- the Las Vegas-based quartet brought the house down with its retro-tinged romp. Talk about a missed opportunity: The next time the Killers played Denver, they sold out the Fillmore, just like the Strokes.
