I've noticed several times this error, in additional notes or in recording info.

In Italy "GR" stands for "Grosseto", a Tuscany province. So don't write things like this:

"Recorded at Studio X, Roselle, Greece", if you see in booklet or site of the local band the above mentioned letters (usually written "(GR)", after another city/village name, part of that province), because it's not Greece, it's Italy.

A good method to avoid such errors, it's to leave the exact writing that you see, so if you read "GR" (or "(GR)"), leave that, without "translate" in Grosseto or Greece.

Thank you.
