So you say you want absolute metal insanity? The type that drives you so absolutely bat shit, and in the end, you’re crawling on the concrete, all bloody, bruised and scarred? Are you free all day today? ‘Cause if you are, then the lineup today at JR’s will satisfy your craving. In the afternoon, West Philly’s keytar brandishing heavy metal authority Mose Giganticus, along with Adgegacea, Halo of Snakes, and Horseburner, will storm the South Philly neighborhood bar with their guttural howls, beefy guitars and drum wallops (read The Deli’s recent “Where Is My Mind?” interview with Mose Giganticus’ Matt Garfield here). And if you’re not done with the sonic thrashes, go grab a bowl of pasta and stick around for the evening show with local noise daredevils Heavy Medical and let their amplified brand of buzz-drunk guitars, bass ferocity and berserk drums seep into your tarnished soul (of course, bill mates Amps for Christ, Orphan, Kuschty Rye Ergot, and Serpents of W.I.S.D.O.M. will also help out with that). You’ll thank me later. JR’s Bar, 2327 S. Croskey St., 2pm & 8pm, $5, All Ages (Mose Giganticus Photo by Jana Miller) – Annamarya Scaccia
