Ricky Skaggs has paved the way for many of today’s newgrass players. He’s helped keep bluegrass both relevant and rooted, always staying true to his style, but at the same time looking to expand his boundaries through working with the likes of Jack White and Emmylou Harris over the years. Skaggs is a true pride and joy of a long and winding American genre, probably because of his more than 40 years of dedication to perfecting his craft. Oh yeah, and he is an absolutely wicked mandolin player. $30. 7 and 9:30pm. 316 S. Main St. 734-761-1818. www.theark.org.
