So it’s a pattern that’s been seen innumerable times throughout history- a woman and her guitar. But Rachel Zamstein’s pop-rock gems are not to be overlooked, a fact proved by her recent bookings along the east coast and as far away as Stockholm. Her debut album, “Bouquet” features her melodies backed by a full band in true rock ‘n roll fashion, with jazz infusion in her soulful vocals, a demonstration of her influence from her grandfather, a professional jazz musician. See Rachel at Rockwood Music Hall on January 10. – KB
