Canadian country vocalist Corb Lund rides the line between roots musician and radio-ready crooner. While his guitar playing may be too gruff to go against Kenny Chesney or Keith Urban, there’s an undeniable charm in his voice. Half the battle with country music is selling the artist as the genuine article; Lund is about as home-cooked as they come. With the Deep Dark Woods, Frontier Ruckus. Tractor Tavern. 8:30 p.m. $13. 21 and over. DUSTY HENRY
