John Bohannon's Ancient Ocean is filled with shimmering ambiance made from guitar and samples. Building from silent humming tones, guitar melodies and delicate tonal drones envelope into lush soundscapes. Moods are similar to Stars of the Lid and various solo works of Kawabata Makoto, but carry their own majestic quality. As the album progresses, the longest track features Daniel Carter on saxophone and adds a tender experimental jazz element to the brooding guitar textures.
