A niche band from Asia I loved as a teenager disbanded in the early 2000s. Due to legal reasons their work is in forever limbo, no Spotify, official YouTube etc. Best you can get is 2nd hand CDs on online marketplaces for a premium.
One guy was seeding a 4GB torrent over on PirateBay from 2008 with every song, music video, numerous interviews etc. Reasons like this is why pirating needs to stay alive. Legend made me want to seed it with him longterm. Now we’re 2 seeders strong.
Keep sailing pirates, and whenever possible please seed.
OPs case might have even be easier to solve by using search terms in the respective language. Might not have been the same result and more manual work but maybe satisfactory results.
From what I understand the (Japanese) band official wrote the band name with the Latin alphabet. The band had a slight international presence in France if I’m not mistaken with their 2nd last album getting a limited CD release, so maybe a pirate site catering more to the Japanese or French crowd might have yielded better results in hindsight.
