I seriously would like some help buying the
'Roots Search' soundtrack on vinyl / record / LP
And CD.

I think there is a chance that it seriously might
Be one of the most rarest anime OSTs in the world
I might need some help from you guys and a middle man service
And I might even have to ask the person who composed
It if they are even still alive and I would need to find someone
Who speaks JAPANESE.

Can anyone help me ?

I have a FLAC rip. I am listening to it now but I want the real thing.

you can't buy it. A friend had to buy in some Osamu Shoji japanese fan website. She bought it not the vinyl but in CD.
I made a entry in VGMDB (http://vgmdb.net/album/33359)
They ripped it from vinyl and recorded in CD. Since she did not even saw even the vinyl for sale. As a collector, yes you might want the real deal, but at least now we can finally have the music. Digital, not physical, but better then nothing.

What if I personally asked the composer / creator of the Album like I did with Moran Fisher the creator of the Twilight Of The Cockroaches OST

Do you think that might work ?

it's worth a shot. But the problem stands. You won't have any more vinyl still made.
So unless the man has his own stock of stuff that was not bought, then you might have hyper luck on it.

Could you please give me as much contact info as you can for the composer / creator / musician who did the score / soundtrack for the anime ROOTS SEARCH please ? I am going to attempt to buy a copy of the vinyl from him myself.
