For the true live-music connoisseur, quality sound might be the most important element of a concert experience — even the actual quality of a band's performance takes a back seat. Think about it: Shoddy sound can quickly and completely ruin a night out at a club and have you cursing the waste of the hard-earned $8 that got you in the door. On nights when Ryan Adams mans the controls at Off Broadway, showgoers can rest easy. Adams, a product of Webster University's audio program and the drummer for indie-pop darlings Gentleman Auction House, takes full advantage of the great natural acoustics of the venue, letting pleasant frequencies shine while dialing out unwanted hiss, squeals and squelches. And like any good soundman, Adams knows how to push the PA, making the kick drum thump, the vocals shimmer and the bass rumble, all the while taking care to cut out those nasty, unwanted, tinnitus-inducing squeals.
