Did you just play this for the first time? Just straight from feeling?
It's really calming and a joy for my ears. I really love the high pitched notes at around 3:40! And then at 4 min when they harmonize! Like the power is building up the entire song and it gets unleashed.. the accident... the SOS.. Then it fades away, as no one comes to rescue, and the world turns dark.
I love how a song can tell you a story.
