Top 10 Metal Musicians Who Are Relatives
Matt married Jon's sister (or Jon married Matt's sister? )
Brothers, founders of the band Savatage.
Jon - great singer
Criss - amazing guitarist, who died too young, at 30. R.I.P.
PS. Ron - I already made a list that showcases Ron's mad guitar skills: "Top 10 Blotted Science Songs". Ron influenced most of the technical death metal guitarists, most notably Muhammed Suiçmez of Necrophagist.
Bobby - Rob Halford said that Bobby Jarzombek is the best metal drummer he knows.
Brothers

Best Death Metal couple!

@IronSabbathPriest - it isn't subjective and I agree with you. Officially, one of their subgenres is heavy metal but they are not known for the songs that may be considered metal. They are known for MTV-friendly poppy rock songs. It's complicated...
I don't really think of this as metal. But that may be subjective... I don't know.
