Before things mellow out at Elena’s Soul Lounge tonight for their Thursday Nite Chill with DJ Paulie Paul, it’s going to get a little sci-fi weird with extraterrestrial sounds from improvisational prog/jazz/noise/math/rock power trio Many Arms. Led by Deli favorite scary Twilight Zone shredder Nick Millevoi, the mood will be anything but chill during their set at the West Philly watering hole. The band recently signed to John Zorn’s Tzadik label, and will be dropping a full-length album next year. They’ll be joined by noisy pop-tinged rockers Banned Books, West Philly punkish metal outfit Split Red (who will debuting new frontman Justin Duerr from Northern Liberties), and headliner NYC’s Little Women.
