To be clear, this is Fallout 4's score, which was composed by Inon Zur — not the soundtrack of licensed music, such as hits by The Ink Spots, that plays on in-game radio stations. The 65-track score runs for more than three and a half hours, and comes in a box set of six blue vinyl LPs in three full-color gatefold jackets. Only 3,000 sets are being produced, according to the product page in the Bethesda Store.
Interested parties can pre-order the Fallout 4 Deluxe Vinyl Soundtrack for $125; it is scheduled to be released July 1. The back of the package can be seen below.
