The loose collection of rock superstars known as Kings of Chaos will soon join up for a good cause. The group, which has a core of Slash, Matt Sorum, Duff McKagan and Glenn Hughes, will team up with Sammy Hagar on July 29 at the Fillmore in San Francisco. Also participating in the concert are another former Guns N' Roses member, Gilby Clarke, Myles Kennedy, and Billy Duffy of the Cult.

This show will raise money for Ric O'Barry's Dolphin Project, an organization which, according to their website, "aims to stop dolphin slaughter and exploitation around the world."

Last month the Kings of Chaos performed at the Grand Theater at Foxwoods in Mashantucket, Conn. They were joined by Robin Zander of Cheap Trick and Billy Gibbons of ZZ Top for a night that saw the musicans jamming on each others' hits with some choice covers in between. Kings of Chaos has promised more shows throughout 2015.

Tickets for the show, which are $75, will go on sale Friday, June 12 at 10AM Pacific. You can buy them at the Fillmore's website. There will also be a silent auction.
