When the West Philly Orchestra takes the stage at Tritone tonight, it will be the usual high-energy Balkan dance party that you are accustomed to, but on this special evening the mood will be filled with a little medieval enchantment courtesy of the Oubliette Ensemble. The pragmatic West Philly folk quintet has taken their music to the renaissance fair on last year’s self-titled debut Sacre et Profane. And when the interwoven sounds of harp, accordion, mandolin, flutes, cello, and more combine with the serene voices of Cynthia James and Melissa Santangelo, it makes for one mystical experience. So while the combo might not look like a perfect match on paper, their old-world charm will certainly win you over. Tritone, 1508 South St., 10pm, $5, 21+ (Jordan Shayer) – Bill McThrill
