Acoustics Anonymous have a problem. But only when they can’t find a groove, which, fortunately for us, is exceedingly rare. The St. Louis-based quintet — which features guitarist and Burlington expat Drew Jameson — trade in a heady cocktail of bluegrass that mixes equal parts tradition and jam band sensibilities. Touring behind their debut album, Honest & Wild, AA begin a residency at Nectar’s in Burlington on Wednesday, July 2. They’ll be at the House That Phish Built Every Wednesday in July with locals Cricket Blue.
