Officials said they were satisfied with the inaugural concert that was being held at the Kai Tak Arena on Friday, saying it had generally met the government's expectations.

The show was aimed at testing the venue’s readiness for hosting mega events and its possible impact on the surrounding neighbourhood.

Around 5,200 ticket holders attended the Chill Thai Music Festival, which featured local boy band Mirror, girl group Collar and various Thai performers.

The performance kicked off at around 6.50pm -- 20 minutes behind schedule -- and ended at 10.45pm.

A spectator surnamed Wong said while the acoustic system wasn’t perfect, instructions were clear and staff were helpful.

"To be honest, since it's the first time, there's room for improvement. I'd give it 50 marks," she said.

"Everything was clear and plenty of people were helping out. When we went in, people voluntarily helped us check our tickets and find our seats. There were also many signboards, and this place was easy to find."

"We needed to wear Airpods to protect our ears because the music was too loud," another spectator, surnamed Chan, said.

Commissioner for Sports George Tsoi -- who attended the test event with Secretary for Culture, Sports and Tourism Rosanna Law and Acting Secretary for Security Michael Cheuk -- said authorities were generally happy with how things went.

"The show today slightly overran, but we have systems and mechanisms in place to handle such situations, including communication protocols with public transport operators," he said.

Tsoi added that various audio and visual setups will continue to be fine-tuned to improve overall spectator experience.
