I want to know the answer to the following question:
What US heavy metal band is comprised of Armenians?
All the background I'm provided with is that "Richard Hagopian is perhaps the most famous artist of the traditional "kef" style and the Vosbikian Band was notable in the 40s and 50s for developing their own style of "kef music" heavily influenced by the popular American Big Band Jazz of the time.". Is that enough to answer the question?
