DJ Anthony Pappa has evolved from his progressive roots into a somewhat deeper, more techno-inflected sound on his recent releases — still polished and melodic, but with a slightly edgier and perhaps somewhat darker vibe. Whatever idiom he's worked in, he's been a consistently solid jock throughout his career while somehow flying largely under the radar — at least compared with some of the artists that emerged at the same time he did, such as Steve Lawler and Danny Howells. Despite lacking the kind of name recognition that some of his peers have amassed, Pappa's accomplishments are impressive. He's released entries in popular DJ series including Balance, Global Underground Nu Breed, Renaissance and React, and collaborated on original productions under the names Freefall and Pappa & Gilbey. His latest effort — the DJ mix Moments 2, on his own Red Light District label — was just released, and the promo tour brings him to Vinyl this Saturday, September 12.
