Andrew Alli plays the blues. The Richmond singer and harmonica player has the spirit of Sonny Boy Williamson and Little Walter flowing through his veins. Like those legends of the instrument and form, Alli’s loose, soulful take on the blues is based on feel. He’s able to make the listener stand in his shoes. A dedicated and engaging player and performer, the Richmond native’s take on classics and his own compositions are what playing the blues is all about. On Friday, Dec 4, Alli and his backing band the Mainline bring eyesight to the blind at the Savory Grain. The music begins at 8 p.m. Free. thesavorygrain.com.
