If you’ve yet to experience the soul-grooving, body-moving, spirit-soothing sound of Teagan and the Tweeds, you don’t know what you’re missing. Don’t let their collegiate-clad name fool you; this band is anything but stodgy and conservative. A six-piece ensemble that includes a Hammond organ and pedal-steel guitar, the Tweeds rock a blues-country-folk vibe that fills a venue like nobody’s business.
