When the swing craze of the last decade hit, it was as if the world had finally caught up with the jump-blues grooves Roomful had been working since its early incarnations. The band's grip on vintage R&B and rock and roll is just as strong. Mastery of classic standards is tough enough, but the Roomful crew can write 'em as well. In particular, Guitarist Chris Varchon -- who took the reins around the time of Turn It On! Turn It Up!, the band's mid-'90s Grammy-nominated disc -- has emerged as a solid tune-crafter. His contributions to the band's new offering, Standing Room Only, range from hard swing to streetwise R&B to torchy blues. Roomful's power on disc strongly suggests that it'll be raising the roof this weekend at Wilbert's.
