Sammy Hagar And Kirk Hammett Tease New Song Collaboration, ‘The Seven Sisters’

Inspired by Sammy Hagar‘s interest in extraterrestrial phenomena, a potential musical collaboration with Metallica guitarist Kirk Hammett might be in the works soon. Hagar shared on Ultimate Classic Rock‘s UCR Podcast that the song, which already has a working title, is expected to have a supernatural vibe.

“You know who’s a big fan of all of that? Kirk Hammett from Metallica. We’re writing a song right now called ‘The Seven Sisters.’ Well, we’re not writing it [yet, but] we’re talking about writing it,” Sammy said. “‘The Seven Sisters,’ which is the Pleiades, where a lot of these people are coming from. For the ride out of the song, we’re going to go into [part of] “Silver Lights” [from Hagar‘s 1976 solo album Nine on a Ten Scale].”

In July, Sammy Hagar and Kirk Hammett are set to reunite on stage at Ozzy Osbourne and Black Sabbath‘s farewell concert in Birmingham, England. The singer has already revealed which Ozzy track he plans to perform at the event.

Separately, Hagar recently released a new single, the heartfelt “Encore, Thank You, Goodnight,” via Big Machine Rock. This melodic rock anthem, co-written with Joe Satriani and inspired by a dream, features reflective lyrics and dynamic musicianship.

Inspired by a vivid dream Hagar had about the late Eddie Van Halen, the song marks a full-circle moment in his storied career. “Encore, Thank You, Goodnight.” features Hagar on vocals, Michael Anthony on bass, Joe Satriani on guitar and Kenny Aronoff on drums. The production — handled by HagarSatriani and Eric Caudieux — delivers a sound that is at once nostalgic and forward-looking. According to Hagar, the dream that sparked the song came about a year after Eddie‘s passing and left a lasting impact. Rather than being a somber farewell, the song is a celebration and expression of appreciation — for the fans, and for the unforgettable chapter they shared in VAN HALEN.
