Infusing the jam and soul scenes with southern twang, JJ Grey & Mofro have carved out a niche for themselves over the years. The band’s last album, Ol’ Glory, delivers all the goods: passionate vocals, relentless rock structures, swampy flourishes (like the slide work on “The Island”). Live and in-person, these guys bring heat to the stage, presiding over dance parties in venues across the country -- another perfect antidote to the past week’s malaise. And, when it’s time to tone things down a bit and reflect, Grey’s more recent introspective and sober tunes -- “Light a Candle,” “Every Minute” -- will give us all a nice chance to recognize the good will that still drives us.
