What's one of the most famous lead singers in metal supposed to do when her band's power system goes down?

Apparently, the answer is audible to a crowd singalong to Journey's "Don't Stop Believin'."

In the first of what will be a busy couple months for Lubbock's rock and metal music fan base, Thursday night's show at the Lonestar Amphitheater brought the smoke — and not just what was emitting from In This Moment's stage production.

Before Maria Brink could serenade the concert goers with her version of Steve Perry's words, the Cherry Bombs — a unique acrobatic entertainment outfit — opened the festivities and were quickly followed by Sleep Token, a burgeoning four-piece group that dons all-black outfits, aside from the lead singer's face mask.

Following Sleep Token's set, the Amphitheater crowd started the first singalong of the night when John Denver's "Take Me Home, Country Roads" came over the PA system. Before the second chorus could conclude on the former Texas Tech University student's top hit, Nothing More interrupted the fun for their hour-long set.

Nobody seemed to mind. Fronted by the highly energetic lead singer Jonny Hawkins — who performs without shoes and soaked through his thin hoodie three songs into the set — Nothing More ensured the crowd a good, loud time.

Midway through their frame, Hawkins ditched the hoodie — as is his custom — and finished out the set topless. Sprinkling in songs from their forthcoming album "Spirits," which is due out on Oct. 14, Nothing More had plenty of long-standing hits to get the crowd going, including "Turn It Up Like (Stand in the Fire)," "Jenny" and closing out with "This is The Time (Ballast)."

In This Moment made their way to the stage just at 10 p.m. and began their 90-minute set. Though the band is slated to release a stripped-down version of their classic album "Blood" later this year, there was no lack of energy, even with the near dozen costume and set changes throughout their set.

One thing's for sure: Maria Brink knows how to put up a show, even when she has to improvise.

During one song, Brink was seen looking at the stage crew and gesturing to her ear, walking off the set shortly after. In This Moment's band power system — which provides backing tracks, the extras that make the band's songs stand out, and the internal communication between members and crew — had gone out.

"What in the hee-haw hell is going on?" Brink jokingly asked.

About 10 minutes of chatter and discussion passed before Brink asked the in-house crew to put on the classic Journey hit. At first, it was the crowd singing to Brink, but she took control after a while.

Issues were eventually resolved, and the rest of the show went off without a hitch.

Thursday's show was the first in what will be a string of some of top acts in rock and metal coming to Lubbock. Next up is Wednesday's show at the United Supermarkets Arena with co-headliners Korn and Evanscence. Then, on Sept. 23 back at the Amphitheater, will be I Prevail, fresh off their new "True Power" album.

The fun continues on Oct. 2 when Grammy-winners Halestorm headline at Buddy Holly Hall while Nov. 1 will see the trio of Motionless in White, Ice Nine Kills and Black Veil Brides bringing the Trinity of Terror Tour to the Amphitheater.

In This Moment and Nothing More were a pretty good way to get things started.
