The 2000 film Requiem for a Dream celebrates its 20th anniversary this fall, and in that time there's at least one part of its legacy that's never faded: the music. The movie's haunted original score spawned a kind of breakout hit that would ripple through media for years to come, while also kickstarting a new career for its British-born composer, Clint Mansell.

Rachel Portman has been scoring films since the 1980s, and in 1997 became the first woman ever to win an Oscar for best original score for her work on Douglas McGrath's Emma. Since then, Portman has scored dozens more films and TV shows, but is now stepping away from the screen with ask the river, her first album of music not written for a movie, TV show or stage production.

"There were hardly any female film composers," Portman says of winning an Oscar at that time.
