II. The Regulators are the real deal. These wild eyed southern boys from Southern California play honky tonk, blues-infused, good-time boogie tunes kick started by harmonic layers of gut-bustin’ guitars.
This Sextet delivers a unique blend of downhome American music as exemplified on their new Southbound Records CD entitled “Regulators Bar & Grill”.
