As if August weren’t hot enough already, a dozen bands will be massing at Oregon Ridge Park on Aug. 18 to heat things up even more. With three stages hosting acts simultaneously, there’s bound to be something pleasing to your ears (and maybe a couple other senses, as well). Participating musicians include The Revivalists (pictured), Trampled by Turtles, Psycho Killers, Karl Denson’s Tiny Universe, Nikki Hill, the Cris Jacobs Band and more. The music starts at 11:30 a.m. at the park, 13401 Beaver Dam Road in Cockeysville. $73-$199. hotaugustmusicfestival.com.
