The exciting synergy between 'Fourth Generation Representative Vocal,' Swan, and 'Sentimental Producer,' Jung Key, has come to fruition. Swan recently released her debut solo single "Twenty (Prod. Jung Key)" on the 2nd, which was gloriously embellished by Jung Key's participation in the overall production.

Jung Key, the producer, has emerged as a 'hit-maker,' delivering a string of hit songs such as "Alone," "Forgotten," and "Sincere." Borrowing the voices of various artists such as Lim Se-jun, Kim Na-young, Yuju, and Jeong Seung-hwan, he has showcased deeply emotional music. Jung Key sees himself and the singer as a three-dimensional relationship, co-completing a single piece of art. With his subtle sensibility, he maximizes the charm of the singer to create the most beautiful sound.

In this context, Jung Key caused a collaboration syndrome with high synergy with Wheein. Their 2017 release, "Anxious," captivated the public with its poignant breakup sentiments, proving its popularity by topping the music charts for a long time. Furthermore, the song achieved the unusual feat of winning first place on SBS's "Inkigayo" on March 26 of that year, without appearing on broadcast. The pair, known as a 'tried and true combination,' swept the top spot on the music charts with "Let's Break Up," released after two years and six months, and recorded a hit streak, proving their worth.

Following Wheein, Jung Key's new muse has appeared - Swan from Purple Kiss, who has made her mark as a 'top idol vocalist.' Jung Key staged a performance with Swan in the KBS2 producer battle program 'Listen-Up' broadcasted last September, and Swan drew standing ovations from the audience with her unique, distinctive vocal color on the grand stage. It was a noteworthy moment with Jung Key betting on an electronic sound rather than a ballad and Swan's interpretation that implemented his intention 200%.

On the 2nd, the two came together again for Swan's solo debut single 'Twenty (Prod. Jung Key)'. 'Twenty (Prod. Jung Key)' is a single that contains the story of Swan turning twenty. Jung Key took charge of the overall production of the single, and Swan also participated in the lyrics of all the songs on the first single, melting complex emotions such as excitement and fear felt while turning twenty.

Swan sang a hopeful message through the title song 'Twenty (Prod. Jung Key)', encouraging everyone not to be afraid of becoming an adult and to freely unfold what they want. Swan's dreamy and mysterious tone combined with Jung Key's lively yet heartwarming sound left a lasting impression. The pop R&B genre track 'Be my everything' also highlighted Swan's color with a minimalist sound. Swan, who depicts the twenty-year-old in full bloom, is raising expectations by announcing that she will showcase the first performance of the title song 'Twenty (Prod. Jung Key)' on Mnet's 'M Countdown,' scheduled for today (6th).

Jung Key and Swan, who proved their synergy once again while decorating a meaningful page called solo debut, have different musical abilities and their future actions are expected to shine even more.
