Gabriel is Michael Tremonti.
He has posted at the Pit for quite sometime now. People from the Pit have met him in person. He is a very nice guy. His girlfriend Denise also posts occasionally and they both update us on stuff Mark is doing, and they will often put rumors to rest.
Do you have to believe me? No. But I am one of the 3 women who was at the Meet & Greet, and so far everything I've posted has been proven to be true.
(Oh, o.k. I got a little confused on the heavy metal project part, but Michael straightened me out.)
