The WNC Jewish Federation presents two fundraising events this weekend: A discussion with author Scott Bernard titled “Jews, Blues and Rock ‘n’ Roll,” on Saturday, and a concert at the Orange Peel featuring rock musician Peter Himmelman and Asheville’s own Skinny Legs And All on Sunday. Check out an Xpress interview with Himmelman, who talks about his creative process, the challenges and inspiration of keeping the traditions of his faith and his “I’m just going to wing it” performance style.
