The mysterious vinyl, titled '----- / ------ / ------ / XXXXXX / ------ / ------', was first released as a secret Record Store Day release back in 2013. It was produced as part of a cryptic marketing ploy, promoting their album Tomorrow’s Harvest.
There are only three physical copies of this record known to be in existence, with one of them being previously sold for $5,700 on eBay. Other Music, a record shop in NYC, received two of the three copies, as stated on the Discogs page that has since been removed. One was sold on RSD while the other remained in their possession, that is until it was apparently sold today.
