Over the last decade or so, My Bloody Valentine frontman Kevin Shields has needed merely to mention the idea of a new album in order to provoke a revived interest in shimmery, fuzzy, blaring early-’90s shoegaze. Now that Shields has made good on his threats of an MBV reunion, a lot of current bands could be considered a little redundant. It certainly puts Philadelphia-based experimentalists Relay in a tough spot. On one hand, a band could do worse than to be compared to My Bloody Valentine, as Relay often is; on the other, Relay is genuinely inventive, taking the Valentine formula and adding a few new tricks to it. The twinkles, twirls, and swells of electronic ambience that sometimes underpin Relay’s sonic atmospheres are delicate and unobtrusive, and the quartet’s yawning surges of sound and understated vocals distinguish it from the comparison du jour. RELAY PERFORMS WITH TIMBERWOLF DIVISION, GIRL LOVES DISTORTION, AND HIMALAYA AT 10 P.M. AT THE VELVET LOUNGE, 915 U ST. NW. $8. (202) 462-3213.
