It all began on New Year's Eve 1981, when guitarist Jimmy Nace and his older brother — drummer and lead singer David Nace — played their first show with bassist Tim Williams. Ever since, the Nace Brothers Band has reaped a sturdy grassroots following over the course of six albums. (There's a seventh in the pipes.) The band primarily plays blues but lays down thick, jammy grooves alongside the slinky whir of T.J. Erhardt's Hammond organ. (There's also fiddle-driven bluegrass and country twang.) The crisp, lively playing is a joy to watch, but the highlight is David Nace's soulful singing, delivered with a rough-hewn swagger. The legacy has been handed down for three generations. The brothers' father, Johnny Nace, scored two big regional hits ("Blue Notes" and "Midnight Train") in 1968. Their grandfather, Percy Nace, was a bluegrass fiddler, and his father, Valandingham Nace, was a classically trained violinist. You know what they say: like father, like son.
