Everyone says it. EVERYONE. You have to see this guy live! You have to! YOU! Reignwolf is Jordan Cook, and Jordan Cook is the real deal—a Canadian, blues-traveling shred master who works a fret board like a 666-word-per-minute secretary taking notes for the devil. Reignwolf sets are often a one-man-band affair—Cook growl-singing, guitar-gnarling, and drum-pounding with every free limb—but a few friends just might join the performance, freeing him up to stalk the stage and treat the crowd to a wicked, sweat-soaked solo. You HAVE to see Reignwolf at the Neptune—he’ll be sure to blow the house down. (Neptune Theater, 1303 NE 45th St, www.stgpresents.org, 9 pm, $16, all ages)
