Seems to be a well-known album in some underground scenes, but I just found #Fishmans #LongSeason. And wow, I like it.

It's basically a single 35 minute track. It was described as being "dream like" / #psychedelic which I think fits quite well. The singer, who unfortunately passed away already, uses #Falsetto which adds another unique touch. It's from 1996.
