Quick is not Atlantic Line. Their music is a sneak attack on your subconscious. Whether it's an eleven minute space journey called The Voyage Home or the speeding train track anthem of Big Brother, these tunes will incite drug like visuals into your daydream before you can realize what's happening.
Soaring, cinematic, spacey, rocking, and an anthem to the sublime can all be used when describing Atlantic Line's sound. The best thing you can do is just pass along the album and let everyone figure it out for themselves.
