Hi,
At the end of the 90's I got a disk with some metal/rock tracks,
including a song that I remember the intro - here is a record of this intro.
Main melody (also of the song itself) at 0:52.

Thanks in advance!

It sounds slightly like Nothing Else Matters by Metallica. There are elements of it in there at least.

No, It's some heavy metal song

But "Nothing Else Matters" is a heavy metal song.

I'm not really an export in these types..
So I guess it's more death metal black metal etc.
