GATLINBURG, Tenn. — Nearly four decades after first bringing its unmistakable yellow-and-black brand of hard rock to the national stage, Stryper showed at Monsters on the Mountain that the sound behind one of rock’s most distinctive bands remains remarkably strong.

Taking the stage at the Gatlinburg Convention Center on August 20, Stryper delivered the soaring vocals, heavy guitars and harmonies that have defined the band since the 1980s — with a live performance that was about considerably more than nostalgia.

Stryper still sounds exceptionally good.

Frontman Michael Sweet’s vocals were one of the night’s standouts. The range and high notes so closely associated with Stryper’s music remain firmly in place, backed by the guitar work and vocal harmonies that helped make the band immediately recognizable during the height of the 1980s hard-rock era.

And Stryper’s history is more significant than the yellow-and-black stripes might suggest.

The band has sold more than 10 million albums worldwide, with its landmark 1986 album To Hell with the Devil achieving multiplatinum status. The album became the first Christian metal release to achieve platinum certification and helped push a band with an openly Christian message into a mainstream rock world where that kind of crossover was largely uncharted territory.

By 1987, that crossover was impossible to ignore.

Videos from To Hell with the Devil became fixtures on MTV. “Free” and “Honestly” each reached No. 1 on Dial MTV, the network’s viewer-request countdown, and Stryper became the first band ever to place two videos in MTV’s Top 10 simultaneously.

And those weren’t the album’s only MTV success.

The video for “Calling on You” reached No. 2 on Dial MTV, giving To Hell with the Devil three videos with major exposure on the network. “Honestly” also crossed into mainstream radio and became Stryper’s biggest pop single, reaching No. 23 on the Billboard Hot 100.

For an openly Christian heavy-metal band, it represented a significant barrier being broken.

Stryper wasn’t confined to Christian radio, record stores or church audiences. The band was appearing on the same MTV screens and competing for the same rock audience as the biggest acts of the era. Contemporary coverage at the time documented that expanding mainstream acceptance, while Stryper’s success helped demonstrate that a band could remain explicit about its faith and still compete in the commercial hard-rock market.

More than three decades later, much of the lineup responsible for that legacy remains onstage.

Michael Sweet handles lead vocals and guitar alongside original guitarist Oz Fox, while Michael’s brother, Robert Sweet, remains behind the drums.

That family connection has been part of Stryper from the beginning. Michael and Robert Sweet formed the earliest version of the band together before the group ultimately became Stryper, making the brothers part of a musical partnership that now stretches across nearly four decades.

Veteran bassist Perry Richardson, formerly of FireHouse, completes the current lineup. With Michael, Robert and Fox, that puts three original Stryper members onstage in Gatlinburg.

And visually, there is absolutely no mistaking who is up there.

The yellow and black remain everywhere — from the instruments and clothing to the band’s enormous logo towering over the stage. It’s an image Stryper made its own decades ago, and seeing those striped guitars under the stage lights remains one of rock’s more recognizable sights.

But the presentation would mean considerably less if the music behind it didn’t hold up.

It does.

The guitars were heavy, the harmonies were intact and Sweet’s voice remained a centerpiece of the performance. Rather than sounding like a band recreating something that worked in 1987, Stryper sounded like a band that still knows exactly what it does well.

There’s another reason this isn’t simply a trip through Stryper’s past.

The band is preparing to release The Final Battle, its 14th studio album, this fall. The upcoming record continues a recording career that began in the 1980s and has kept Stryper creating new music alongside the catalog that established its legacy.

Plenty has changed in rock music since Stryper first appeared in yellow and black. MTV doesn’t occupy the place in music culture it did when fans were requesting “Free,” “Honestly” and “Calling on You,” and the hard-rock landscape that surrounded To Hell with the Devil belongs to another era.

Stryper’s significance within that era is secure. The sales, the platinum album and the unlikely MTV crossover made sure of that.

What Monsters on the Mountain demonstrated is something different.

The history is impressive. The band standing onstage in Gatlinburg is, too.
