Hollywood's weekly rock collective Ultimate Jam Night has stepped up repeatedly for the music community, and they'll continue to do so this week with a show in honor of David Z., the Adrenaline Mob bassist who was recently killed in a tragic bus accident while the band was on tour.

This week's performance features the Ultimate Jam Night regulars of Quiet Riot's Chuck Wright, Mr. Big's Matt Starr, MSG's Mitch Perry and Survivor's Walter Ino with an increasingly growing lineup of special guests. Ultimate Jam Night has been hosted by Paul Zablidowski for some time now, and Zablidowski is the brother of the Adrenaline Mob bassist.

Dee Snider, Sebastian Bach, Eagles of Death Metal frontman Jesse Hughes, The Winery Dogs' Mike Portnoy, Poison's Rikki Rockett, King's X's Dug Pinnick, Jeff Scott Soto, Ron "Bumblefoot" Thal, KISS' Bruce Kulick, the Wood Family, Bullet Boys' Marq Torien, Trans Siberian Orchestra's Roddy Chong, Lynch Mob's Sean McNabb and Duran Duran's Joe Travers will all be on board for this Tuesday's (Aug. 1) performance.

Doors will open for at the Whisky-a-Go-Go on Aug. 1 at 8PM and the Ultimate Jam Night performance will be broadcast on Zinna.Tv. Stay up to date on the Ultimate Jam Night additions here.

To continue his legacy, a David Z. Scholarship Fund has been created for the music school at Brooklyn College. Head here to donate.
