Ebb and Flow is a split EP of gesturally rhythmic ambient music built from field recordings and other noise sources. It doesn’t have a beat, per se, but it draws percussion into the mix. Half of the EP is by Stabilo and the other half is by Gallery Six. Both Stabilo (aka Yasutica Horibe, of the band Speaker Gain Teardrop) and Gallery Six (aka Hidekazu Imashige) are based in Hiroshima, Japan. The highlight of Ebb and Flow is “Endurance,” which balances a twinkling percussive element, like a vibraphone being played by tiny rubber balls, amid water drops and a thick sonic fog. Gallery Six’s “Vapor” is more textural than its title may suggest — it’s like the sound of a thousand pachinko machines playing from deep in some flooded cistern. There are four tracks in all, and the full set is highly recommended.
