Theresa Mercado doesn't take horror movies lightly. The slasher-film guru has programmed the Scream Screen series for more than a decade, delighting and horrifying audiences along the way. But her cultural expertise goes beyond film, as Mercado brings Denver's best experimental musicians in for pre-show, mood-enhancing sets at the Sie FilmCenter. Acts like Blood Loss, Echo Beds, City Hunter and DJ Sara Splatter have set the tone for events like the Scream Screen Scream-A-Thon, when Mercado played all four Scream films back to back, or the weeks-long Birthday "Slash-ebration" series honoring Tobe Hooper, director and producer of such classics as Texas Chainsaw Massacre, Poltergeist, The Funhouse and more.
