Olan Mill are Alex Smalley and Svitlana Samoylenko who work with a somewhat restricted set of acoustic instruments. Echoes of piano, violin, pipe organ, guitar are present but these are often wrapped in dense layers of reverb, their respective edges blurred to create rich and vivid sonic spaces.
Occasionally complex layering gives way to a much more stripped down sound often being lead by stunning piano motifs. For the most part though, cinematic, sweeping layers of sound create rich and fulfilling moments. Moments that you should experience and immerse yourself in as soon as you can.
You can find Olan Mill here. Enjoy.
