I just looked up the word rabiz on the Internet and it came up with the following:

"Rabiz (n). A slang word describing a social class of Armenians that exhibit socially questionable behaviors." It then goes on to describe rabiz music; "ironically, is an adaptation of Turkish songs adapted for a rabiz-Armenian audience."

It also accuses Rabiz's of smelling strongly of onions!

Hate to condemn anyone before I've heard their music but it sounds to me as though it might be the music of an urban social underclass, rather like rembetika or fados. In which case I doubt that I'd dig it, and I doubt that it would sound much like the Azerbaijani music on World routes.

I'd be glad to find otherwise though.
