Although it is an omnibus work, it is a Japanese-planned compilation that feels like an original album.
This work was released in 1979. Until then, it was necessary to listen to multiple albums to get a full collection of the 1958 session recordings, but with the release of this work, it became possible to listen to each session individually from the same period. In that respect, it is no exaggeration to say that this is an original album.
When this album was first released, all tracks were mono. Later, after a search, the original 3-track stereo multitape was discovered. Since then, all re-releases have been replaced with stereo tracks.
