If your objection to Dirty Dancing is that it’s just not dirty enough, don’t miss the chance to see two purveyors of sweat-soaked primal raunch get scuzzy and fuzzy on one double bill. The suavely unkempt Tav Falco, who resembles a used-car salesman stepping out of a John Waters film festival, is the rockabilly equivalent of a bulldozer with no brakes. Although the trashman kitsch can wear pretty thin on record (even when the producer is a former Panther Burn named Alex Chilton), live Falco’s band works hard for the money. The fine mess that results is especially recommended to those hard-of-hearing types who think the Cramps have “sold out” by tuning their instruments too much. Make sure you arrive early, because I’m betting on Chicago’s own Sapphires to steal the show. Like Jeff “Monoman” Connolly’s Boston bands, the Lyres and DMZ, the Sapphires mine the depths of 60s grunge-guitar memorabilia with such conviction that they sound as fresh as tomorrow. The band’s new debut album, quite possibly the coolest record ever made in Glenview, may also be the most exhilarating collection of post-Nuggets throb rock since the Lyres’ On Fyre a few years back. Along with Green and others, the Sapphires are ushering in a Chicago garage renaissance that is already rivaling the glory days of the Shadows of Knight and the Cryan Shames. Tonight, Cubby Bear, 1059 W. Addison; 327-1662.
