Explosions in the Sky is a post-rock instrumental group who are most known for supplying the soundtrack to the movie Friday Night Lights. Before then, though, every fan of Explosions... felt like listening to their music was akin to listening to a soundtrack for a movie that has yet to be made.
For writers -- or any creative type -- this band and their music can help stir some inspiration and emotion into the writing. It's especially helpful since the band doesn't use any kind of vocals in their songs.
Listening to First Breath After Coma when I'm get stuck with writer's block or if I can't figure out what to paint or anything, it helps me visualize what I'm emotion I'm trying to convey. The way it builds slowly is beautiful and no matter how many times I listen to it, I'm constantly carried away.
