Royal Machines, the band featuring Dave Navarro (Jane’s Addiction) on guitar, Billy Morrison on guitar, Josh Freese on drums and Mark McGrath on vocals, performed last night at The Roxy in Hollywood, CA and Sebastian Bach joined them for a cover of “Mountain Song” by Jane’s Addiction. Bach takes the lead vocal with McGrath and Donavan Leitch on backing vocals.

In a new feature at GQ.com former Skid Row frontman Sebastian Bach discusses his new autobiography, 18 And Life On Skid Row, and trades hair care secrets with Jen Doll.

Jen asked how Sebastian has managed to keep his tousled golden mane so rock-perfect since the ‘90s, to which he replies: “It's like a lawn. Just fucking leave it. Let it go. Do you ever see bums with short hair? No, they’ve all got kick-ass long fucking hair, lying in the street. Fucking let it be a bum.”

His wife, Suzanne is sitting next to him. “We use keratin,” she says. Bach interjects: “If you must know the truth, at my age it's necessary for me to have the Brazilian blowout.” He runs his fingers through his hair. “This is the Brazilian blowout, ladies.”

18 And Life On Skid Row released on December 6th through Harper Collins. To coincide with the release, a string of "author events" are underway in the US., with one date remaining on December 17th at 9 PM at Hard Rock Hotel in Las Vegas, NV. Go to this location for additional information.

In his memoir, Bach recounts lurid tales of excess and debauchery as he toured the world with Bon Jovi, Aerosmith, Mötley Crüe, Soundgarden, Pantera, Nine Inch Nails and Guns N' Roses. Filled with never before seen photos from his own personal collection, 18 And Life On Skid Rowis the story of hitting it big at a young age, and of creatively reeling from a band that broke up in its prime.

From a man who achieved his wildest dreams, only to lose his family, and then his home, this is a tale of perseverance, of wine, women and song, and of a man who has made his life on the road. 18 And Life On Skid Row is not your ordinary rock memoir, because Sebastian Bach is not your ordinary rock star.
