The mellowness of DC in the middle of August provide some excellent opportunities for local musicians. Tonight DC’s blues troubadour Jonny Grave headlines the prestigious 9:30 Club with support from Derek Evry & His Band of Misanthropes and Olivia Mancini & The Mates. Jonny, Derek and Olivia are three very different musicians who share a love of the city and its musical scene. If you don’t yet know them personally, you might be surprised at the level of enthusiasm these talented personalities are going to generate at DC’s finest venue tonight. For a Friday afternoon warm up, watch Jonny Grave perform “Tear Me Down”, from his 2013 solo album The Hammer, live at the Corcoran in the Salon Doré last year. See you tonight, obviously.
