This is the original soundtrack of the incomplete 1994 sci-fi OVA *Yamato 2520*, by the jazz musician David Matthews. Converted from an APE rip found on Squid to FLAC for more universal playback. In addition, the file track names are in English (the metadata remains unchanged and has the Japanese track names); translation from VGMdb.
There is another APE lossless rip on nyaa, dating from 2012, but it is unseeded. If anyone has the scans from that torrent, please let me know (or just seed the torrent).
