In August, a new drag show — called My Oh My — will launch, and every Monday night, you can jaunt on down the House of Blues for a live performance. But before that happens, there’s casting to be done! Local drag performers (and hopefuls) are invited to audition tonight starting at 7:30. But these are open auditions, which means you don’t have to have an act get get into the act. Members of the public are free to attend and watch the talent. And it’s free.
