SAN FRANCISCO — Underoath brought a no-nonsense, take-no-prisoners attitude to its Friday set at the Warfield. The Florida rockers led a megabill of punk, metalcore and hard rock that took on the flavor of an old-school Warped-Tour-style format. Each of the trio of opening bands played a 35-minute set with quick changeovers, while the headliners topped out at around 70 minutes. Touring in support of its ninth album, Voyeurist, Underoath leaned heavily into its newest material while also including a fairly even array of its back catalog as well.

Vocalist Spencer Chamberlain wasted little time in attacking the stage for ferocious opener “Damn Excuses,” and the pace barely wavered through the first portion of the set.

The band powered through “Breathing In a New Mentality” before bringing a small synth keyboard on stage for Chamberlain to play on the brooding “On My Teeth.” The mosh pit was active for songs like “It’s Dangerous Business Walking Out Your Front Door,” as the crowd screamed along with the tag team vocals of Chamberlain and drummer Aaron Gilespie.

“We haven’t been to San Francisco in more than two and half years,” Chamberlain said, pointing out the disparity at multiple points along the way.

Chamberlain generally kept his banter brief and to the point, turning his focus more on getting the crowd moving. Underoath kept the stage design fairly straightforward, with the band backed by multicolored beams of light shooting toward the ceiling of the venue. Slowburner “To Bright to See, Too Loud to Hear” was a rare slower track (until the explosive conclusion).

“It feels very much like the band is getting back together,” Chamberlain said. “Dreams are coming true to be able to do this again.”

In one of the more introspective moments of the evening, he thanked fans for sticking by the band through a pandemic, internal strife and member changes, as the band broke up, then reformed in 2018.

Underoath was nothing but energy from the first notes, with keyboardist Christopher Dudley providing the activity on stage, dancing and head-banging, while drummer Aaron Gillespie matched Chamberlain’s harmonies blow for blow. After a brief encore break, the band returned for the one-two punch of “Thorn” and “Writing on the Walls.”

“We’ve got two songs left and this is the first one you guys voted for in an online poll,” he said as he introduced “Thorn.” “So if you don’t like that, it’s your fault!”

When the concert was first announced, Every Time I Die was the support act, but the band broke up before the tour began, which is not conducive to being an opening act. So instead, Underoath found two of the hottest hard rock bands on the circuit at the moment: up-and-comers Spiritbox and Bad Omens.

Canadian heavy rockers Spiritbox had a heavy contingent of fans at the show and didn’t disappoint, starting with the heavy, churning “Rule of Nines.”  Birthday-girl vocalist Courtney LaPlante brought a compelling presence to the stage. While she could do amazing things with her voice, from sunging to guttural screams, LaPlante was an interesting presence who almost didn’t seem aware of her own incredible talent.

“I was going to come out here and say some hardcore boy shit,” LaPlante joked as she grabbed the bouquet of flowers presented to her in celebration of her big day. “And then you went and gave me these.”

The band traded off aggressive heavy metal with melodically sung vocals on tracks like “Circle With Me” and “Hurt You” as strobed pulsated all over. Based on the entirely unscientific test of T-shirts in the crowd and of merch line length, it appeared that Spritbox is in the midst of a fiery rise.

LaPlante thanked the crowd for supporting the band, saying she’ll never take for granted the opportunity to play for an audience. Spiritbox closed out its set with “Holy Roller” and “Eternal Blue.”

Bad Omens is another hard rock act on the way up. Vocalist Noah Sebastian and his Virginia quartet brought an even more eclectic set, ranging from the most melodic of electro-pop to hardcore thrash.

Its performance opened in dramatic fashion, with Sebastian taking the stage by himself to sing the melody-heavy intro portion of “The Death of Peace of Mind.” Then, one by one, the remainder of the band walked out. The band played a fairly even split between its new album, The Death Of Peace OF Mind, and 2019’s Finding God Before God Finds Me.

Just like SpirtitBox, Bad Omens’ sound was sonically varied and well-constructed, shifting from infectious melody to ground-swelling heaviness almost instantly.”Like A Villain” proved to be one of the highlights.

Stray From the Path opened up the evening with an impressive set of punk-inspired hard rock. The band is seasoned, having formed in 2001 and with 10 albums under its belt. To picture its sound, imagine what would happen if Rage Against the Machine and Papa Roach came together.

“Facists and racists aren’t welcome here,”  vocalist Thomas Williams announced early in the set. Williams also spoke of San Francisco as being one of the places where punk rock and counter culture got its start.

The band’s set was driving and heavy, and informed the conversation of what follow.
