It's called an open mic, but it's more of a loosely run jam. Drums, PA and some back line are provided. Signed in players perform 3 to 5 songs. Other skilled musicians might jump in to back you up. Genera range from classic rock to folk to blues to a young lady attempting to sing an Ariana Grande song while being backed up by several 60 year old guys who just gave the song a listen on their phones. It's all fun and everyone is encouraging.
