It’s been another hard fought contest, but the field has now been narrowed to four in the third installment of the Artvoice.com Battle of Original Music (BOOM). Once again, local music fans have spoken by visiting our Web site week after week to voice support for their favorite acts. On Saturday night at the Sportsmen’s Tavern, our four finalists will square off in a live battle royale from which only one act will emerge victorious and claim a recording package from Sessions Recording Studio, market-ready CDs of that recording courtesy of ESP CD and DVD Manufacturing and, to leave a more lasting memory, $150 worth of ink for each band member from our friends at Art-n-Body, Inc. At the event, audience members will each be given one ballot to cast a vote for their favorite band. Will it be Sam Gillam, London vs. New York, Off the Cuff or Host Echo? When the ballots are counted, one of them will join previous BOOM winners Dali’s Ghost and Constant Climax in the year-end BOOM Grand Finals, to be held immediately after the next round of the contest. The prize pool is growing for that ultimate showdown, and acts interested in winning the fourth and final spot should submit their materials for consideration next week at Artvoice.com. Come out and celebrate the local music scene with us at another great live music venue.
