Bohemian Rhapsody (Old, unknown cassette source)

Any information of this?? find this in youtube and don't know nothing more

Curious ... My initial thought would be a multitrack mix ?? Altered to sound like a mangled up tape ??

My opinion is the same as Reid_Special_98. Sounds like a multitrack mix with some filters through it to make it sound like shit haha.

Yeah the bass guitar sounds a little TOO clean to cut through like that

To me this should be a faked demo. But clearly an after Boh Rhap multitrack leak demo.
