Most shows are raucous in nature, but sometimes you just want to sit back, sip your cocktail and listen. And for those moments, it’s nice to know that Carol Covell and her trio is there for you every Tuesday night at 2113 Bistro. The longtime Richmond vocalist invokes Sarah Vaughan’s fluid grace with a grit, charm and gusto that swings and swaggers in a manner befitting comparison to the legendary jazz singer. Her interpretations of the great American songbook have their smoky charms intact. And for an era when crude bluntness rules the pop music day, her sultry seductions are a timely reminder that romance is best experienced as slow burn. The Carol Covell Trio plays Tuesday, Jan. 21, at 2113 Bistro, from 7:30-10:30 p.m. Free. 2113main.com.
