If you believe the press hype so far, Boston singer-guitarist Susan Tedeschi is the latest great white hope of the blues scene. A 27-year-old graduate of the prestigious Berklee College of Music, she and her band finished second in the 1994 National Blues Talent Competition in Memphis. However, on her debut, just won’t burn, Tedeschi flames brightest on the least bluesy numbers. The rockabilly flavored “Rock Me Right” and a couple of self-penned ballads display the raspy sensuality of her voice better than the closing homage to Muddy Waters or the standard bar-band renditions of a Junior Wells tune and songs associated with Ruth Brown and Bonnie Raitt. At 9:30 p.m. at Twist & Shout, 4800 Auburn Ave., Bethesda. $8. (301) 652-3383. (Steve Kiviat)
