Thor, that’s the album I mentioned in my list. It consists new recordings of selected cues that were recorded for a collection of outtakes Toho put together for home video release. It’s the closest to a film score Ifukube worked on during the 1980s.
I actually have video from the recording sessions. There are some rather funny moments too. One instance was Ifukube almost lighting a cigarette at the filter end (I’ve done it too), and the other trying to get his lighter to work trying to light another cigarette, only to give up after a few attempts (another thing I can relate to). The session video also features an outtake not on the album.
By the way, the CD issues feature more music than the LP.
