gAr reminds me of GWAR. People will sign up expecting you to
shoot koolaid out of a cannon while in some sort of 'where the wild
things are' costume.
Of course, there might just be a market for that somewhere. :-)
gRa-volti audio rolls off the tounge a bit better than gAr-volti, and IMO sounds more italian. (understanding, that;s not the goal, but if it's going to sound like something... might as well go for it)
Greg Roberts Audio GRA may also be a prefix, romance-languae wise, meaning 'greater'. (may)
No googling done.
