The guy has a hell of a voice. He makes Sandman sound quite fresh even and that takes some doing.

His Adele is even great.

He's like a young Jorn.

I don't know Defecto. What style is this?

I know Nicklas Sonne from the latest Section A

and the new Theory album

Same guy. Defecto is melodic prog metal. Theory kicks ass of course. Defecto came out last year. They ended up winning the vote to support Metallica recently.
