The American rock band was formed in 2001 by lead vocalist Brandon Flowers, guitarist Dave Keuning, bassist Mark Stoermer, and Ronnie Vannucci Jr on drums.
We imagined the band's biggest fan base would be teenagers and young adults. But the band's increasingly mature style of music also lured a bunch of older fans to Kitec, creating a pretty wild vibe.
The band opened with their massively popular debut hit, Mr Brightside. This set the tone for the evening: anthemic, shout-along, head-bobbing tunes followed one after the other.
The two-hour set featured most of the big hits - Smile Like You Mean It, Read My Mind, Somebody Told Me - with the band displaying incredible energy throughout. The electric atmosphere was enhanced by the crowd, who matched the Las Vegan musicians' vigour. Even if you weren't a massive fan before you went in, it was impossible not to give into the infectious good mood.
Possibly the best performance was Human. The lyrics were inspired by Hunter S. Thompson, an American journalist and writer, who criticised his country for raising "a generation of dancers". Flowers asks "Are we human, or are we dancer?" in the hit song - and yes, we all sang along.
Towards the end of the show, the band performed one of their best loved songs, All These Things That I've Done, which features the famous line "I got soul, but I'm not a soldier". Flowers' passion was met by that of the fans, who chanted the same line over and over with him. Even after the concert ended and people headed home, the line could still be heard being hummed incessantly - almost like an echo - by fans.
The 18-song set was enjoyed by established fans and curious attendees alike, no doubt sending hundreds of people racing to buy or download their music and see what else they've been missing.
Flowers, too, was delighted by the night, saying: "It took us 10 years to come to Hong Kong. Let's hope that it won't take us 10 more years to come back."
