South Korean R&B singer DEAN brought the house down at Flash Factory in New York last weekend. Although DEAN's first concert in NYC didn't come without a few hiccups including a last minute venue change. (The show was originally set to happen at the Copacabana.)

After waiting in line for at least three hours, fans were forced to find their way twenty blocks downtown to gain a place near the stage again. According to the production company that handled the concert, SIVA, the famed Copacabana had technical difficulties including sound issues. A lucky hundred fans were able to meet, greet and take a photo with DEAN before the announcement though.

But nothing, not even waiting in the rain, could stop fans from seeing their favorite singer take the stage -- especially since it's unknown when the international star will be back on this side of the world again. And after a successful soundcheck at Flash Factory, DEAN's manager with the pull of Creative Artists Agency and SIVA's on-site staff were able to pull off a miracle by securing a new venue within an hour. Not to mention, the new digs allowed them to sell an extra 200 tickets for the originally sold-out show.

Instead of 7 p.m., the showtime was pushed back to 9 p.m., but it didn't take long for the hour-and-a-half show to begin. DJ Prince, who was called in on short notice, set the mood for an already hype crowd with some of today's biggest trap music hits. Then, SIVA's first artist, Milan, took the stage to perform some catchy hip-hop tracks. The young rhymer, who performed in New York for the first time over the weekend, was the Top 9 contestant from rap competition, Show Me The Money LA during its fifth season.

Afterwards, another impressive rapper by the name of Cheech Bundy took the stage. The native New Yorker layed bars in his short performance including the Illmind-produced "This is 4." "I'm happy ya'll are f------ with the real hip-hop," he said to the cheering crowd. But there was only so much more waiting the audience could do for the main act of the night. Like DEAN's producer name, Deanfluenza, his fans are crazed with their love for the 23-year-old singer. And for good reason.

DEAN took the stage shortly before 10 p.m. to a happily screaming mass of about 1,000 people. It was just him and his adoring fans when he said the two words that his fans have been waiting to hear: "Let's go."

He started off with the smooth Anderson .Paak-featured hit, "Put My Hands on You." The song, which had every audience member singing along, has gained over one million views on YouTube. "We're here, it's time to turn up right?" he asked the crowd who readily screamed "yes" back.

It wasn't long before the space became intimate as red hues overlayed DEAN as he serenaded the crowd and worked his way through his debut EP, 130 Mood: TRBL. Not only did he provide smooth tones with "Half Moon," "What to Do" and "Bonnie & Clyde," DEAN provided some killer gliding moves during his performance of "21." But it was the last song that brought the full concert all together -- the Eric Bellinger-featured track, "I'm Not Sorry."

In the song, DEAN boasts that he's "just getting started" and that he's "turning up" -- just as the up-and-comer asked the crowd to do in the beginning. But of course that wasn't enough for his fans, so it wasn't long before they were screaming for an encore. DEAN luckily obliged and came back to perform the last track from his EP, "I Love It."

While DEAN would normally stay and take pictures with his fans, the last minute change prevented him from doing so -- something that DEAN's manager was disappointed about. "We're appreciative of the Flash Factory and CAA for accommodating us. We would have loved to stay and hang out with the fans and take pictures. However, because it was booked on such short notice, Flash Factory already had another event planned and one of the conditions was that we had to get out as soon as the show ended," said DEAN's manager, Jeffrey Yoo. "We are so sorry and at the same time we're very appreciative and humbled by what the fans in New York City endured to make this show a success."
