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
