EXO's main vocalist, Chen, has once again solidified his reputation as the "Vocal King" in the K-pop industry. Recently, he took on the viral "Crazy" riff challenge, showcasing his exceptional vocal prowess and leaving fans and netizens in awe.

Chen, who recently wrapped up his first solo tour in Japan titled "Polaris," has been in the limelight for his outstanding vocal performances. The tour spanned five Japanese cities, including Yokohama, Osaka, Okayama, and Kitakyushu, commencing in Nagoya on August 19. Throughout the tour, Chen presented a diverse setlist of 20 songs from various genres, including hits from his Korean solo albums such as "Beautiful Goodbye," "Shall We?" and "Best Luck." The tour was a testament to Chen's immense popularity in Japan, with fans even organizing a surprise birthday celebration for him during his Kitakyushu performance.

However, it was after the tour, during a special birthday event, that Chen truly captivated fans and netizens alike. Videos from the event showcased Chen taking on various challenges and dance covers, including STAYC's "Poppy" and the TikTok-famous "Snowman" challenge. But the highlight was undoubtedly his attempt at the "Crazy" Riff Challenge.

The challenge, which originated from Sia's song, requires singers to perform a 40-second verse in one breath. While Chen showcased his impeccable vocal skills, he humorously failed the challenge multiple times during the performance. Yet, it was his rendition of the "Crazy" Riff Challenge that truly stole the show. The challenge involves singing the song's first line with a high riff, raising its note six steps higher. Not only did Chen master the high notes, but he also stunned fans with a six-step low note rendition, showcasing his incredible vocal range.

Fans were quick to share videos of Chen's performances, with one particular video combining his high and low register renditions, creating a harmonious masterpiece. The videos went viral on TikTok in no time, reigniting the popularity of the challenge that first emerged in 2021. Chen's exceptional vocal range left not only K-pop fans but also general internet users in awe, reinforcing his status as an unparalleled "Vocal King" in the music industry.

Social media was abuzz with praise for Chen, with fans expressing their admiration for his vocal talents. Tweets like "WOW CHEN'S VOCALS IS REALLY INSANE" and "I really love chen's vocals  it's sooo beautiful... always making me smile whenever I hear him sing " flooded Twitter, reflecting the widespread appreciation for the singer.

In the ever-evolving world of K-pop, Chen continues to set the bar high, proving time and again why he is considered one of the best vocalists of his generation.
