Fiddler and step dancer April Verch began her career wondering how seasoned players could get a crowd dancing, but now the focus is on her own feet. Verch credits former Ashevillean Casey Driessen, producer and engineer of April Verch Band’s 10th album, The Newpart, with the idea to write a song specifically for these two underpinnings of her career. He built and miked a wooden structure, which Verch stomped and tapped away on with metal, wood and leather shoes. “What works visually is completely different when it’s only audio,” she says, calling the process of writing her song, “Gilchrist” a fascinating experiment. “What I thought was a great move turned out to be way less effective when you couldn’t see the step. It forced me to think of my feet as purely an instrument.” Verch’s trio plays a roots set at Isis Restaurant & Music Hall Thursday, Oct. 29, at 8:30 p.m. $15/$18. isisasheville.com.
