Hopefully this stirs a little more interest and discussion.
Ray Alder's voice took me a long - LONG - time to appreciate. I still don't 'get' some of the early FW stuff, but really love his work with Redemption. Matos is an absolute beast with Angra (I prefer his era to Edu's... but not by a whole lot), and delivers an unreal performance on The Flying Opera. I don't know his other works, but have no doubt he delivers there too.
I'll take Matos' range over Alder's grittiness.
