The influence of Sterling Sound mastering engineer George Marino will be felt for years to come as rock's biggest acts have to turn to someone new to handle future albums. After learning of Marino's death, rockers like Slash, and members of Metallica and Anthrax were quick to share stories that celebrate his career.

"We will miss him terribly. He was the best. RIP George," Slash said on his Twitter page. Metallica's website also featured a nice tribute: "His talent, professionalism, attention to detail and above all true dedication to music, along with the mere fact that George was simply one of the nicest people we have ever met anywhere in the music business, makes today a very sad one for everyone in the Metallica family."

Metallica's legendary 'Black Album' was one of the legendary record Marino had a pivotal role in producing. He also worked on Guns N' Roses' 'Appetite for Destruction,' AC/DC's 'Back in Black,' Bon Jovi's 'Slippery When Wet,' Journey's 'Frontiers' and many more classic projects.

Anthrax also issued an official statement on Marino's impact:

"R.I.P. George Marino. Any decent collection of heavy metal and hard rock will be full of records he mastered. He mastered 'I'm the Man,' 'Volume 8,' 'Return Of The Killer A's,' 'We've Come for You All,' and 'Anthrology.' It's also fun to say he mastered 'Master of Puppets.'"

Anthrax drummer Charlie Benante added, "He made the long hours up at Sterling, interesting and fun. I would leave there thinking we just did something great. With George it was all for the music. He had a great set of ears! We lost a master craftsmen and a great man. I will miss him a lot!"

“R.I.P. George Marino, we will miss you,” Chickenfoot guitarist Joe Satriani tweeted.

Marino was a three-time Grammy winner, most recently in 2011 for Arcade Fire's 'The Suburbs,' which won Album of the Year.
