There’s a (17 minute) C64 song that I’ve been waiting years for someone to post in a format that can be easily shared. It’s “Delusion” by Kjell Nordbø. It’s the 15th track on this music disk, which Nordbø mailed to a friend in 2005 just before taking his own life.
I ripped the song to MP3 ages ago for convenience and I should probably just put it on YouTube myself since no one else seems to be doing so. It’s really something.
