This is a less famous Italian Verdicchio from an official Italian region that is selling for about US$12 to 16 in the US now.
If you mean the heavy metal rock group Metallica, I do not know of wine sold under their name. However there are some old rock groups that have wine and even an absinthe sold under their name. There is a note in the Oct. 2011, Decanter that says that AC/DC and Warburn Estate now produce some AC/DC wines named for some of their hits such as "Highway to Hell" Cabernet, "You Shook Me All Night Long" Moscato, and "Hell's Bells" Sauvignon Blanc.
The same issue of Decanter has a cartoon of a couple in a restaurant with a bottle of AC/DC wine on their table. The man says: "If it's anything like their music we'll wake up tomorrow with a thumping headache".
