It’s been so gratifying watching Block B‘s Park Kyung rise to prominence as a solo artist. In an idol group with a leader as incredibly successful as Zico, it’s not easy to stand out, but Kyung has always been my preferred member due to his entertaining persona and lighthearted, cleverly constructed music.

Last year he gave us one of 2015’s best duets, teaming with Park Boram for Ordinary Love. With Inferiority Complex (자격지심), he once again pairs with a female vocalist. GFriend’s Eunha gives an uncharacteristically light performance, raising the key to sing in a higher pitch that adds an element of innocence to the track. The two trade between verses and chorus, offering an effective push and pull that keeps the song fresh throughout. The instrumental borrows many of the same effects used in Ordinary Love, but it has a bit more bounce to it. Kyung’s post-chorus refrain is especially effective, standing as the song’s catchiest moment. As expected, the hip-hop verses crackle with interesting turns and a sing-songy delivery that feels perfectly in line with Complex‘s indecisive sentiment.

What Park Kyung does best, as evidenced in both his solo tracks so far, is inject his material with an incredibly endearing, underdog personality. A track like Inferiority Complex, which is as much a mini-drama as it is a pop song, lives or dies on the performer’s ability to connect with the listener and feel as approachable as he is charismatic. The song is certainly catchy, but it also feels like a conversation, with all the highs and lows and twists and turns you would expect. At this rate, I wouldn’t mind if he paired with every female idol in the industry, producing chapter after chapter in what’s starting to feel like a truly enjoyable series.
