Tuesday marked what would have been the 50th birthday of the late Alice in Chains vocalist Layne Staley.

To mark the occasion, the band have created a short documentary which features tributes from Jerry Cantrell, Heart vocalist Ann Wilson, and Layne’s Mad Season bandmates: Pearl Jam guitarist Mike McCready and Screaming Trees drummer Barrett Martin.

“Layne, to me, was one of the greatest singers in rock and roll history,” says Cantrell in the video. “I’ve never heard anything like him before and I will never hear anything like him since.

“Just to be able to get to be in a band with a guy that does that to you, there’s nobody better to me than him and he’s my friend.

“When we started playing together and writing tunes, mostly I was just kind of doing back-ups, I didn’t want to sing, anyway – we’ve got him, we’ve got that guy and he’s pretty good, you know.

Staley died on April 5, 2002 of a drug overdose. He was only 34.
