Debut With “Hookga”


For background, HIGH4 20 was a sub-unit from the boy group HIGH4 that was formed under N.A.P Entertainment in 2014. The group consisted of two members only, Alex and Young-jun. They were known as the rappers of HIGH4. HIGH4 20 debuted on October 3, 2016, by releasing the debut single “Hookga.”

Alex and Youngjun participated in the music production, and they strived to make an extraordinary single that sounded different from other music. For the choreography, they collaborated with a famous foreign choreographer, according to Youngjun.


In an interview, Alex explained that their agency loved the single “Hookga” and wanted it to be released. That was one of the reasons HIGH4 20 has formed. Aside from the single “Hookga,” there’s also another single titled “Weekend.” Both “Hookga” and “Weekend” are in the hip hop genre. An interesting fact about “Hookga,” it was a collaboration single between HIGH4 20 and MAMAMOO’s Hwasa!

The collaboration suited their music nicely since Hwasa is also known for her amazing rap skills. Previously, N.A.P Entertainment was released several teasers for HIGH4 20’s debut single, but the teasers only showed Alex and Youngjun. Then, in the third teaser, it was finally revealed that Hwasa was featured in “Hookga.”

Individual Teaser Images and Music Video

N.A.P Entertainment made the fans more excited and eager by releasing several teaser images and teaser videos for “Hookga!” Through the individual teaser, both Alex and Youngjun look effortlessly good-looking and charming. Their style included leather jackets, jeans, chain accessories, sleeveless tops, leather boots, and more!

Music Video for “Hookga”

The single “Hookga” was released alongside a music video on October 3, 2016. In the MV, Alex and Youngjun appear in various styles that emphasize their strong and manly charisma! At first sight, they look like some cool guys who went to a secret party after finding an MP3 player.

Some people might think that their style is similar to a gangster style. Moreover, in the scene with Alex and Youngjun dancing with a bunch of dancers, their vibes look even more similar to the gangster and punk image.

Alex and Youngjun’s style for the “Hookga” MV gained a lot of attention. Their manly appearance was supported by casual outfits such as denim jackets, plaid shirts, ripped jeans, sleeveless tops, and dark hoodies! Their rock style also shows through their straight, dark hair and accessories. The “Hookga” MV also shows a mixture of monochrome and vintage colors. For its setting background, there are several places we can see including a warehouse, workshop, suburban area, walls of graffiti, and a nightclub.

Then, the appearance of Hwasain the MV was also very eye-catching! Even though we could only see her half appearance at first, it was still amazing. While listening to Hwasa’s deep and sexy voice, we can watch the secret nightclub scene with them having fun together.
