Don't do that again. Ever. The accordeon was not made for Black Sabbath.
That's not to say you did poorly, although the rhythm was off, but that song should never be played on accordeon.
That's different...
I'm always a fan of an "innapropriate" instrument being used in rock music though that's not the greatest of such substitutions I've ever heard, it's certainly quite good. Like any organ, it brings a terrific tonal quality to the song. I'd much rather hear the song on a pipe organ, specifically because such things sound great and are rarely used for rock music.
Keep ruining songs and i might subscribe. This guy has the right idea. Most of the ones he does are unrecognizable. I can't hear the faintest trace of "The End" in his rendition. Impressive stuff.
It's missing all the other obscure intrumenst.
The mouth harp, bag pipes, the recorder, the lute.
The midevil rock band.
Seriously though, it gave me a headache.
