Get on your dancing shoes, Marietta, because Friday night the joint will be rockin.’ Back by popular demand for the third year in a row, the Chicago Blues Party at the Lafayette Hotel promises to be a good time for all. “There’s going to be a lot of dancing. This isn’t the slow, cry-in-your-beer blues,” said Steve Wells, vice president of the Blues, Jazz and Folk Music Society, which puts on this blues event as well as others throughout the year. “We’ve been lucky to develop a good blues audience,” Wells added. “We draw from a good radius — Cambridge, Columbus, Wheeling, Charleston. We’re lucky to get the support.” While it might seem like an odd fit for this area, Marietta has a strong connection with the blues. Wells cites a Feb. 2009 article in Ohio Magazine which calls Marietta “Ohio’s blues cradle.” Along with the annual Chicago Blues Party, Marietta also plays host to the annual River City Blues Festival, coming up on its 19th year.
