I've been returning to this lost ambient masterpiece for about 15 years. I've no idea who made it and am not aware of any other works. Despite this obscurity, it's in my top 10 ambient albums.
The placid, slowly-evolving bass drones of the 30-minute centrepiece 'Siphonophore' descend through the murk into a place of complete immersion and tranquility. Although not 'composed', it still feels like a satisfying musical journey. I'd love to hear more from the talented Hakoneko / droooone!
