A Nonstop Hit-Filled Performance

Following a series of fun games and lighthearted interactions with host Indra Herlambang, CORTIS returned to the stage ready to raise the energy to another level.

The group launched straight into “JoyRide,” instantly sending the crowd into a frenzy.

From the first note, the five members showcased their signature charisma, powerful choreography, and undeniable stage presence. The atmosphere inside Indonesia Arena grew even louder as fans sang and danced along.

Without slowing down, CORTIS continued with “GO!”, one of the most interactive moments of the night.

Thousands of fans enthusiastically shouted “GO! GO!” together with the group, creating a thunderous chorus that echoed throughout the arena.

Fun Challenges, Big Laughs

The excitement wasn’t limited to music.

During a special segment with Allo Bank and host Indra Herlambang, the members participated in a series of entertaining challenges that showcased their playful personalities.

James was first up, tasked with throwing a ball into a backpack worn on his back. After narrowly missing his first two attempts, he finally succeeded on his third try, earning loud cheers from the audience.

Martin and Seonghyon followed in a fast-paced word challenge that tested their rhythm and speed. Both members eventually completed the challenge successfully, much to the delight of fans.

Keonho and Juhoon faced perhaps the funniest challenge of the evening—locating an active camera and striking a pose based on a designated emoji. Their initial confusion had both fans and fellow members laughing, with James even stepping in to help direct them.

By the final round, the duo found the camera quickly, with Keonho confidently striking a muscle-flexing pose that sent the crowd into another wave of cheers.

Sarongs, Batik Scarves, and Viral Dance Moves

After successfully completing all the challenges, the members were rewarded with uniquely Indonesian gifts.

Indra presented the group with traditional sarongs, batik scarves, and iconic vintage rooster cups, all of which the members proudly showcased on stage.

James immediately demonstrated his own creative way of wearing the sarong, placing it over his shoulder and inspiring the others to do the same.

The cultural exchange became even more memorable when Indra revealed the challenge penalty that had been prepared in case they failed: performing the viral dance challenge “Kasih Paham Bos.”

Although they had successfully completed every challenge, the members decided to perform the dance anyway.

Dressed in sarongs and batik scarves while holding traditional cups, Martin, James, Juhoon, Seonghyon, and Keonho enthusiastically danced along to the viral song.

The unexpected moment quickly became one of the highlights of the night, showing just how willing the group was to embrace local culture and have fun with their fans.

“We Will Be Back Soon”

As the evening entered its final chapter, CORTIS returned to the stage for one last set.

They kicked things off with “Fashion,” one of the songs that helped establish their growing popularity, before moving into “YOUNGCREATORCREW.”

Between songs, the members took time to express their gratitude for the overwhelming reception they had received in Indonesia.

“How are you feeling?” Martin asked, only to be met with deafening screams.

“Thank you, thank you. This is crazy,” Keonho added.

“I love it. Thank you, Indonesia,” said Seonghyon.

James also praised the incredible enthusiasm of Indonesian fans.

“Indonesia, we were welcomed with amazing energy.”

Then came the moment that sent the audience into an emotional frenzy.

“We will come back soon. Do you want that?” Martin asked.

The response from fans was immediate and overwhelming.

Clearly moved by the experience, Martin continued:

“Wow, wow, wow. This is crazy. I really appreciate all of you. We’re not even from this country.”

A Farewell Filled with Emotion

For their final song, CORTIS returned to “GO!”, delivering one last burst of energy that had fans singing and jumping until the very end.

As the performance concluded, the members repeatedly thanked the audience for making their first Indonesian appearance so special.

Before disappearing backstage, Martin left fans with one final message:

“I will never forget this moment.”

The arena erupted into cheers as fans waved goodbye to the group that had completely won over Indonesia in just one night.

From explosive performances and viral dance challenges to heartfelt fan interactions and promises of a future return, CORTIS’ debut at Allo Bank Festival 2026 was everything Indonesian COER had hoped for—and perhaps even more.

If the crowd’s reaction was any indication, this won’t be the last time CORTIS takes center stage in Indonesia.
