Ship To Shore Phono Co. succesfully funded a Kickstarter-campaign that allowed them to officially release the orchestral soundtrack to the first game in the MOTHER series (known as Earthbound Beginning in the West).
The Kickstarter is closed now, but they opened pre-orders for non-backers on August 26, 2015 and started shipping December, 2015.
The soundtrack is available in three variants. This is the red translucent vinyl version, which is limited to 500 copies.
