pi (1998)

“Since the movie Pi is a sci-fi psychological conspiracy thriller, the soundtrack itself sounds futuristic, and contains a wide variety of electronic-dance stars alongside three originals by composer Clint Mansell (formerly of Pop Will Eat Itself). Massive Attack's haunting "Angel" is easily the soundtrack's highlight — distorted guitar, ethereal bass, and crisp percussion creep along for six minutes, with Horace Andy supplying the vocals. Also included is the drum duel "Bucephalus Bouncing Ball" by Aphex Twin, the rapid-fire Roni Size dance track "Watching Windows," and the imaginative "Drippy" by Banco de Gaia (dripping water and percussion become merged together). Other contributors include Orbital ("P.E.T.R.O.L."), Gus Gus ("Anthem"), and Spacetime Continuum ("A Low Frequency Inversion Field"), among others.”

Black Swan is a 2010 American psychological thriller film directed by Darren Aronofsky and starring Natalie Portman, Vincent Cassel, and Mila Kunis. The plot revolves around a production of Tchaikovsky's Swan Lake ballet by a prestigious New York City company. The production requires a ballerina to play the innocent and fragile White Swan, for which the committed dancer Nina (Portman) is a perfect fit, as well as the dark and sensual Black Swan, which are qualities better embodied by the new arrival Lily (Kunis). Nina is overwhelmed by a feeling of immense pressure when she finds herself competing for the part, causing her to lose her tenuous grip on reality and descend into a living nightmare.
