The Filter vocalist, who called out Scott Weiland over his sobriety earlier this year, has vowed to stay sober as a way of learning from the singer's mistakes.
Aaron Lewis of Staind, Nuno Bettencourt of Extreme and Brent Smith and Zach Myers of Shinedown all performed separate acoustic covers of Stone Temple Pilots hits.
In one of the most fascinating insights into the man Scott Weiland was, Stone Temple Pilots' former manager recalled some scenes from his time with Weiland.
Two nights before Scott Weiland was found dead on his tour bus in Minnesota, he spoke with Toronto based outlet Live in Limbo, which appears to be his final interview caught on video.
