Don’t adjust your speakers, as the saying goes: Purling Hiss is supposed to sound like that. Across the better part of its recorded output, the Philly shred-core trio offsets hooky, timeless rock and roll songs with caustic, abrasive noise and production values. Which is one hell of a gauntlet to throw down – “we’re going to write this music you’ll immediately love,” they’re essentially saying, “and then we’ll make you work hard to love it.” Fortunately, the payoff is totally there in the end, and if you see the Hiss live before you grab its albums, you’ll find it all the easier to get what they’re doing. This month, the band hits the road with Dr. Dog – getting to play before some well-earned mass audiences – and its last gig before departing is tomorrow night, Jan. 20, at Pi Lam in West Philly. To wish it a good sendoff show and happy / thrashy trails ahead, today’s Philly Local Phile digs into an early favorite from the Purling Hiss catalogue: “Run From the City,” the lead off track on 2009’s Public Service Announcement LP on Woodsist Records. For some compare / contrast fun, see how that number sounds alongside the version Purling Hiss recorded at its Key Studio Session almost a year ago.
