Cosmic adventurer Marshall Allen recently celebrated his 91st birthday. The alto saxophonist and leader of Sun Ra Arkestra continues to prove that his creative nature has no bounds tonight when he teams up Man Man drummer and experimental beat-maker Christopher Sean Powell (a.k.a. Pow Pow/Spaceship Aloha). If you are looking for a rare evening of outside-the-box music, which is brought to you by Ars Nova Workshop (so you know that it will be definitely interesting), then you need to get your ass over to Johnny Brenda's this evening. The two local heroes will be supporting blogosphere darling Holly Herndon, who just released her brilliant new album Platform. Johnny Brenda's, 1201 N. Frankford Ave., 9pm, $15, 21+ - H.M. Kauffman

Whether it’s been from a memory of yesteryear that goes far beyond space or time consisting of him jamming alongside the prolific jazz composer Sun Ra or during his current role of fronting the legendary Sun Ra Arkestra, you have seen/heard incendiary saxophone impresario Marshall Allen perform for a number of occasions throughout the year. But it’s been quite some time, since you’ve had the chance to experience this interplanetary jazz master perform solo. Well, that is exactly what will be happening tonight at The Fire on this very rare bill, which will also feature jazz-noise artisans Extreme Fishkin. And given the improvisational talents of both acts and the number of musicians that they’re connected to, there’s bound to be plenty of unpredictable magic in store. The Fire, 412 W. Girard Ave, 9pm, $10, 21+ - Bill McThrill
