My new Facebook buddy Mordechai Frizis alterted me to a Hassidic Metal band called Metalish. Someone told me about them ages ago but googling them turned up nothing (perhaps due to Haredi prohibitions on internet use?). Anyway, Mordechai told me to go to this Jewish music site that stocks 3 Metalish albums. They give free snippets of the songs that suggests that Metalish perform vocal-less rousing Hassidic dance music in an 80s Metal style.
The search for Jewish Metal continues!!
