Tonight’s bill at Silk City packs a serious combination of punches. The thick psych fog that Harsh Vibes cast is a perfect medium to showcase the downhill-full-steam-ahead-freight-train mentality to execute its brand of heavy. Stoking the fire as they go, Harsh Vibes melds lava-hot guitars, drums that will bash through whatever obstacle that stands in its way, and a bass that refuses to be left behind, while the synth is the tie that binds the vehicle with the destination. True Gold is a band that is sneaky good. While the innocent vocals may lure you into a false sense of the security, a threat emerges when the balanced fuzz and polished guitar is awoken by percussion that lights the fuse. This band doesn’t have to pose to flaunt its muscle. It shows its strength when the music calls for it. Silk City Diner, 435 Spring Garden St., 8pm, $7, 21+ – Michael Colavita
