SACRAMENTO —Saturday night Aftershock line-up was marked by two reunions, of sorts. The night was headlined by The Original Misfits, with vocalist Glenn Danzig and bassist Jerry Only. The reunion, which came in 2016, followed three decades of strife between the two. The group has only played a handful of shows since then, with the Aftershock opportunity coming after initial headliners My Chemical Romance dropped out when they rescheduled their tour to 2022.

The punk rockers weren’t the only notable band coming together again on Saturday night. Heavy metal band Mudvayne performed for just the second time since reforming this summer. The two acts were a double-billing for the punk rockers and metal-heads in the audience. Both frontmen, including Mudvayne’s Chad Gray, were in good spirits throughout the night.

“All those bricks you have pent up from the last two years, those stay outside,” Gray said. “Tonight is about having a good time.”

Mudvayne’s show was a visual spectacle, with three distinct acts. There was a militaristic backdrop, with Gray donning all back and dark silver face paint. Bassist Ryan Martinie, guitarist Greg Tribbett and drummer Matthew McDonough were decked out in black and red designs of their own as the band ripped through opening track “Determined.”

The remainder of the set was a brisk journey through hits like “Not Falling,” “Death Blooms” and “-1.” For the sets second act, Gray reemerged in clown-like attire, attacking the stage with an extreme vocal ferocity on ferocious performances of “Happy?” and “Dig.”

The Misfits put on an extensive production of their own, with plenty of old-school punk energy. Danzig was conversational between most of the songs, keeping in high spirits.

“This is one of our old songs. Well, all of our songs are old, this one is just a little older than the rest,” he said as the band opened with “Death Comes Ripping” and “I Turned Into a Martian.”

The Misfits’ performance included nearly 30 songs with two encore breaks. At one, Danzig joked about the extensive set list.

“We have a long way to go. I’m just going to name off the rest of the songs we’re going to play. You let us know if there’s any you don’t want to hear,” said Danzig, who notoriously doesn’t like to get his picture taken.

Most of those songs came from Static Age and Walk Among Us, with a handful of other records mixed in. It’s possible The Misfits also set the record for the number guitars smashed.

One of the most talked-about sets heading into the day was undoubtedly that of Machine Gun Kelly. The rapper-turned-pop-punk artist has faced a heavy backlash from hard rock fans following his well-publicized spat with Slipknot frontman Corey Taylor. Would Aftershock fans boo MGK mercilessly? Would he even show up? For the most part, those questions came to a relatively anticlimactic answer. Some people booed him, and some through various at him onto the stage, but it wasn’t overwhelming.

“To those who are here for us, thanks for vibing. For those throwing [things], you’ve got bad aim,” Machine Gun Kelly said.

MGK seemed to both welcome and avoid his detractors at the same time. Midway through his set, he pointed out some of the youngest members of the audience, one effective way to not get booed. The singer’s set likely didn’t change any minds one way or the other.

That’s not to say the set wasn’t without its risks. At one point, he climbed up the scaffolding covering the soundboard in the middle of the festival grounds. Given the context of everything, it could have ended badly, but turned into a dramatic moment. On top of his own material, MGK also mixed in a cover of Paramore’s fantastic “Misery Business.”

Security was on high alert, with large body guards flanking each side of the stage. One fan had a large banner reading, simply, “SLIPKNOT” taken by staff.

To his credit, Machine Gun Kelly did ultimately outlast his detractors, with much of the crowd on his side by the final song.

One of highlights of the evening’s undercard came from SoCal rockers The Offspring. The band was tight, effusive and a times downright funny.

“There’s a least 2 million people out there tonight; 2,000,006,” guitarist Kevin “Noodles” Wasserman said. “You can’t forget about those six.”

Opening with “All I Want,” The Offspring played through more than two dozen songs, including all of the hits as well as some newer tracks from this year’s new album, Let the Bad Times Roll. The crowd sang in full force on songs like “Come Out and Play” and “Gotta Get Away.” A surprisingly poignant moment came when frontman Dexter Holland sat behind a piano for a stripped-down version of “Gone Away,” asking the audience to light up the grounds with phone lights. Mixing in songs like “Pretty Fly (For a White Guy)” and “The Kids Aren’t Alright,” the band concluded with”You’re Gonna Go Far, Kid” and “Self Esteem.”

Another highlight of the day went to Atreyu. The band, and particularly Brandon Saller, has played Aftershock in a number of capacities over the years. This year would be a first for the band, given the departure of frontman Alex Varkatzas. Sallor has taken over the bulk of the vocal duties with bassist Porter McKnight handling some of the screams.

Saller’s vocals have always been impressive, but his versatility really showed, mixing sung vocals with screams and even rapping Zero 9:36’s part of “Warrior” for the first time ever.

“I guess I’m a rapper now!” Saller yelled after pulling off the verse to near perfection.

The band kept its set to the hits with songs like “Becoming The Bull,” Ex’s and Oh’s” and “The Time is Now” while keeping it loose and having fun. At one point, Saller even leading the crowd in a singalong of Whitney Houston’s “I Wanna Dance with Somebody.”

“Hardest moment of the festival weekend right there,” he joked.
