North Lawrence Midnight Singers will be celebrating the release of Last Great Saturday Night, which is available for free here, tonight at Johnny Brenda’s. I know. It would’ve been nice to have the show tomorrow, but if anyone has booked a show before at JB’s, their schedule can be pretty tight for openings so you grab what you can. No worries – I don’t think that they’ll be skimping on the heartfelt energy from performing pieces of their latest work for the audience. They’ll be sharing the bill with a couple of local acts who have their own reason to party down tonight. The Josh Olmstead Band and Joseph Arnold are also celebrating the release of their albums, Purple Mountain Majesty In the Antlers Hotel and Discomedusae this evening. Rounding out the lineup will be Steve and Krista Yutzy-Burkey from The Swimmers. Johnny Brenda’s, 1201 N. Frankford Ave., 9pm, $10, 21+ – H.M. Kauffman
