I don't recognize any of these names. I know some actors (like the people who dubbed the original Speed Racer) are still alive and working. Are they among these names?
Do they sing in recognizable voices?
The original songs are hard enough to listen to. Do they really believe that there is a sizeable market to purchase an album of these covers?
You have to follow English dubbing/English language releases of anime to be familar with the people mentioned (Peter Fernendez from Speed Racer is still around and still working.), but Tiffany "Asuka" Grant and Amanda "Rei" Winn-Lee were both on Neon Genesis Evangelion.
Micheal Sinterniklaas has been working on dubbing since the original Bubblegum Crisis came out.
The others are much newer.
