Rare version of Kurenai, this recording never appeared on an album or any other release, rather it was given out in the form of a flexi vinyl inside of a 1988 edition of Rockin'f (ロッキンＦ) magazines. It's a very raw version of Kurenai and the first version sung primarily in Japanese, the only major musical difference being that the intro was done completely in piano instead of guitar, giving it a somewhat haunting beauty. Really unique track. I believe the sonic sheet version gets mistaken for this version. This vinyl was supposedly the only one with the piano intro.
