The folks behind Oskar Blues have a two-decades-long history of hosting live music at their various spots around the state, so it's not surprising that they did a superb job renovating the downtown basement space that was once home to the original Brendan's Pub and, more recently, Pat's Philly Steaks & Subs. Since opening in 2017, they've filled the stage at Black Buzzard with local acts at least three nights a week.
