Signmark.
And who is their Label? My point is that anyone can sing/sign their own song but we are talking about using ASL on other peoples works that have a wide market (i.e. popular, c.w., rock, etc.) and trying to keep the original meaning of the song when translated into ASL. Take the opposite of this with your group Signmark. If this group is totally ASL, would a translation into english be pure to their meaning? I bet not.
