The sub-unit of Girls' Generation, TTS, has made one of their most explosive comebacks yet with their new track "Holler."

Ryan Seacrest, the host of the popular music variety program American Idol and the DJ for the radio station KISS FM, chose the music video for "Holler" as one of the "5 Best Boss-Life Moments in Girls' Generation," according to the Korean publication Osen Entertainment.

"The trio, who originally come from the nine-member girl group Girls Generation, has returned to complete their world domination by releasing their second mini-album, Holler, along with the title track's luxurious and colorful music video," wrote Seacrest on his website.

He added, "The visual opens with a quick scope of a five-star hotel lobby, which includes animations of comic thought bubbles that caption what is supposed to be the viewers' internal thoughts. After the ladies pull a few sexy vanishing acts, the clip delves into a succession of high-energy dance numbers that take place at the hotel entrance and within an indoor oasis."

Soon after the release of their new album, TTS made their comeback performance on the music program M! Countdown, debuting their tracks "Holler" and "Adrenaline."

As expected from the success of "Holler," the trio put extensive thought into the production and fashion seen in the music video.

"We've been prepping this song together, especially "Holler," since late March/early April. We had so many different inspirations and seasonal looks to this song -- we have the spring version, the summer version -- and then it finally got decided for the fall season. So, we went for the S/W colors. There were a lot of ups and downs throughout the project, but we got it perfectly done. We're very satisfied," TTS member Tiffany told Billboard during an interview, revealing that she was the visual director for the clip.

She added, "The video has 10 different outfits -- we wanted to beat 'Twinkle,' that was two-and-a-half years ago, so we wanted it to be a lot more sophisticated. It was very J.Lo-inspired."
