Slipknot has posted a 10-minute tribute video to the band's late bassist Paul Gray, featuring previously unseen footage. Check it out below.

Private funeral services for Gray were held on Friday (May 28) in Des Moines, Iowa.

Paul was found dead in a hotel room in a Des Moines suburb on Monday (May 24). The cause of Gray's death has not been determined, although according to a 911 call, a hypodermic needle and pills were found near the 38-year-old musician's body.

The eight surviving members of Slipknot held a news conference on May 25 at Wells Fargo Arena in the band's native stomping grounds of Des Moines, Iowa to address Gray's death.

Also present at the event was Gray's brother Tony and widow Brenna, who spoke briefly at the end of the conference.

"It's very important that everybody on the outside of us understands that Paul Gray was the essence of the band Slipknot. ... Paul was there from the very, very beginning, and none of us would be on the path that we're on now in life or have the sorts of life that we have without him," percussionist Shawn "Clown" Crahan added.

Brenna Gray spoke last, mentioning the couple's unborn child while discussing her husband.
"Paul was my husband, an amazing person, and I want people to remember him for that," Brenna said. "And his daughter will remember him for the way he was."

Paul and his wife were reportedly expecting their first child in September.
