Legendary guitarist Mark "The Shark" Shelton passed away today, at the age of 60. Mark played guitar for the Proto-Power Metal band MANILLA ROAD.

The band's lead singer, Bryan Patrick made the announcement on social media:

"I'm very sorry to announce today that my long time brother and Best Friend since 1981 has passed through the Halls of Valhalla. Mark W. Shelton may you Rest In Peace! There will be more information within the next couple of days. There will also be a GO FUND ME page set up in order to get Mark back home to his family. My heart is shattered. Please take time today to love your loved ones and hold them close."

Manilla Road played a show in Germany yesterday, July 26th, at the Headbangers Open Air festival and were scheduled to play in Italy tomorrow, en route to Wacken Open Air next week.

Early reports are that Mark died of Heart Failure, but this has not been confirmed.
