Curious who might be on the Warped Tour next year? Chances are they'll play this nearly 4,000-square-foot, all-ages room way up in Spring first — or that they already have. Since JavaJazz relocated from Old Town Spring to its much more spacious FM 1960 quarters in 2006, several of the fastest-rising names in emo and punk-pop — Paramore, Plain White T's, Say Anything, From First to Last — have stopped by. Credit owner and booking agent Michael Kelley's perceptive ears for keeping JavaJazz just ahead of the ever-changing musical curve, and his partner Linda Sporkin for fostering an environment that's half after-school clubhouse, half CBGBs (and thus a frequent stop on the fire marshal's rounds). But mostly credit JavaJazz's clientele, whose ravenous appetite for music keeps them coming back again and again and again. Just remember, no booze; but rest assured there'll be plenty of water on hand since a mosh pit is almost sure to erupt.
