Entering its ninth season, the popular ABC medical drama 'Grey's Anatomy' has long been famous for its use of music, particularly in its montages. To date they have released three CDs of songs featured on the show. Their commitment to music continues on the trailer for the new season, which uses the Cider Sky song 'Where to Now.'

The trailer shows the cast dealing with the aftermath of the plane crash that occurred in the eighth season finale back in May. Characters are screaming, a gurney is being wheeled around the hospital and a man declares his eternal love for a woman. The question "Who will survive?" is asked as they deal with "the most devastating event of their lives."

Cider Sky are a Canadian duo comprised of Simon Wilcox and Shridhar Solanki. Their 2011 song 'Northern Light' was included on the soundtrack to 'The Twilight Saga: Breaking Dawn - Part 1.' In addition to 'Northern Light,' they have also released a six-song EP, 'King,' in 2011. 'Where to Now' has yet to be released on an album.

The season premiere of 'Grey's Anatomy' will be on Sept. 27.
