Hearing a show at the Walnut Room is an audiophile's wet dream. There's no doubt that the room was "built for music," as the club's slogan claims. With over two decades of audio engineering experience under his belt, Ron Gordon clearly knew a thing or two about sound dynamics and acoustics when he helped design the club's sound system two years ago. But having a killer system is one thing; knowing how to make the thing sing is another. Needless to say, when Gordon's manning the faders, you can count on the mix being immaculate no matter who's playing. The guy knows how to make a drum kit kick you in the gut, a Stratocaster swim around your ears and keyboards soar -- all without pushing the volume to deafening levels.
