Watch: STEEL PANTHER Joined By Ex-MACHINE HEAD Guitarist PHIL DEMMEL For 'Asian Hooker' Performance In San Francisco

Former MACHINE HEAD and current VIO-LENCE guitarist Phil Demmel joined STEEL PANTHER on stage last night (Thursday, January 5) at The Fillmore in San Francisco, California to perform the STEEL PANTHER song "Asian Hooker". Video of his appearance, courtesy of Capital Chaos TV, can be seen below.

STEEL PANTHER's sixth studio album, "On The Prowl", will be released on February 24. Drummer Stix Zadinia told Australia's Metal Roos about the LP: "It is killer. Every band, normally you go, 'Yeah, dude, it's killer. It's our best record,' but you know — I think bandmembers know — it's a good record and you believe in it, but you know when you did something… This record has a spirit about it; it has a vibe about it where it's, like… I don't know. It feels different than the last few records. It just feels like there's a lot of joy in this record and fun and rocking and… It's killer, man.

"We actually did it differently than we've done any other record," he continued. "We did it at our houses, except for the drums. And then we had [longtime producer] Jay Ruston mix it. But we engineered this thing — we produced it, engineered it, all just us. Wrote, recorded, engineered, produced. The only thing we didn't do is mix it or master it."

According to Stix, he and his bandmates "were as productive as you could pretty much be as a band" during the pandemic. "We did socially distanced shows, pod shows, drive-in shows, livestreams. I say, 'We didn't do anything,' because… STEEL PANTHER, the way we've come up, we work — we're grinders and we play live. We are producers — we make things, we do things. And sitting on our ass is not comfortable for STEEL PANTHER. So this record is, I think, a reflection of our excitement. And it's gonna be killer."

Last September, STEEL PANTHER announced the addition of Spyder as the band's new bassist.

"Spyder has filled in for Lexxi [Foxx, former STEEL PANTHER bassist] many times," STEEL PANTHER singer Michael Starr told the "Everblack" podcast. "He's a super-close friend of the band. We've known him for years. As a matter of fact, [STEEL PANTHER guitarist] Satchel and I were in a VAN HALEN tribute band for a while, and Spyder was the bass player in that. We have a rich history with him… He did all of Europe with us and he did a great job."

Formed in 2000, STEEL PANTHER specializes in imitating and exaggerating the less flattering aspects of 1980s hair metal, with unrepentantly crude, non-PC sexual content as a favorite lyrical theme.

The group's music has been described as "VAN HALEN meets MÖTLEY CRÜE meets RATT meets 'Wayne's World', complete with operatic shrieks, misogyny, shredding guitar solos and libidinal overdrive."

Fourteen years ago, STEEL PANTHER changed its name from METAL SKOOL to its current moniker and shifted the focus of its act from '80s metal covers to originals.
