Na Zdrove! Upstate blues/soul vocalist Wanda Johnson and Charleston’s own Shrimp City Slim Band (led by keyboardist Gary “Shrimp City Slim” Erwin) usually gig around the Carolinas, but they’ve recently embarked on a big tour of Eastern Europe. The group handle a cool variety of sultry set of standards and originals. Johnson’s latest album, Hold What You Got, features backing from Slim and the guys.

The band’s summer tour winds through Poland and the Czech Republic this week with additional support from the Blues Doctors (from Ostrow Wielkopolski). They’ve already performed at the Suwalki Blues Festival and Blues na Niedzielein Poland. After some additional club dates, they head south for shows in the states of Bohemia and Moravia in the Czech Republic (České Budějovice, Prague, Uhersky Brod, and Tasov). Their next local show is on Mon. Aug. 3 during the weekly blues happy hour from 4-7 p.m. at the Mad River Bar & Grill.
