Who Were The Members of The Beast K-Pop Group and Why did Hyunseung Leave?

The world of K-pop is as diverse as it is ever-changing. Time and time again, groups debut only to have to rebrand and reshuffle its members due to one situation or the other. Beast is one such group that underwent a rebranding. One of K-pop’s most well-known and loved boy bands since they were formed in 2009, Beast would later change to the group Highlight. In an industry where younger and newer bands keep coming and going, Beast/Highlight has certainly achieved things that most boy and girl groups could only dream of; longevity, popularity, and success. But their climb to the top wasn’t an easy one.

Beast debuted in 2009 as an underdog act whose members had already embarked on separate careers or were passed over by other bands. Over the years, Beast grew to become one of K-pop’s most recognized acts, shining with its sleek, energetic approach to dance music and sentimental pop ballads. The group began under the management of Cube Entertainment from inception until 2016.

In late 2016, the group changed management from Cube Entertainment to Around Us Entertainment. By 2017, they changed their name to Highlight. The band’s new agency, Around US Entertainment, told Korean media that the name signifies their potential to be exceptional and stand out. The name is based on the title of Beast’s 2016 album, Highlight, which was the first and only album the band released with all five members in Cube Entertainment.

Why did Hyunseung Leave?

Hyunseung trained for one-and-a-half years to be a part of BIGBANG and was featured on BIGBANG Documentary. However, he was eventually eliminated from the group. He went on to join Cube Entertainment, where he debuted in the six-piece group, Beast. After seven years, Hyunseung left the band in April 2016. Cube Entertainment issued out a statement and revealed that the singer would focus solely on being a solo artist and not continue with his group.

The company wrote that it was due to differences in personalities, which stemmed from conflicting musical opinions. This was to be expected when reports of his lack of enthusiasm during the group’s events and practice sessions started popping up. Around the same time, he also missed out on the group’s performances, even going as far as posting pictures of himself on a date with a woman when the rest of his band was attending a fan meeting.
