What will make Rok Boutique a surefire success is the niche-though-inclusive marketing that makes sure not to exclude those with less-than-metallic taste. With an introduction rather than a come-on, the biker at the bar (every rock bar needs one) starts a conversation with the woman next to him. The vibe is cool and edgy, but Goths and long-hairs become loquacious after a few drinks; no one strives for aloof coolness. Rok is the ideal place for a post-soundcheck/pre-show drink and bite. Even better, head back after the show, settle in, and debate the lightweight, un-glam state of contemporary music. -D.R.
