“fiery, defiant, emotionally charged”
‘Swag Age in Concert’ bursts onto the stage, pulsing with Korean “heung” – infectious, collective joy. Fusing Joseon-era tradition with streetwise swagger, this Korean language musical rewrites history with rhythm and rebellious energy – even if it feels a little lost in translation.
Welcome to a reimagined Joseon Dynasty, where peace comes at the price of silence. Sijo – the poetic soul of the nation – has been outlawed by the elites, leaving the people voiceless. Enter the masked Golbin Gang, rhythmic rebels spreading sijo in secret. That is, until they cross paths with the freewheeling Dan, a rule-breaking prodigy who helps start a cultural revolution. But hidden forces are at play. Will the gang free the people? Or will their swag prove no match for state supremacy?
Produced by Song Hye Sun with book, music and lyrics by Park Chan Min and Lee Jeong Yeon, this is a musical unlike any other on the West End. Blending traditional Korean aesthetics with modern storytelling, ‘Swag Age’ brings sijo to new audiences and a new era. You could argue the main story beats have been done before: persecuted peasants fight oppression thanks to a scrappy resistance group. But it comes stirringly to life through the beautiful songs, layered plot and flawed characters, keeping humanity and art at the centre of the power struggle. Though some things go over my head, such as the peasants’ sudden change of mood in the opening song, Jono’s allegiance to the elites despite his huge secret, and some bulky exposition in the climactic scene. Though this may be in the delivery rather than the writing.
Lee Kyung-soo’s direction makes fantastic use of contrasts. The peasant scenes burst with camaraderie through playful cast interactions, cheerful lighting and harmonious staging, highlighting their strength in unity; meanwhile the court scenes are sombre, static and separate, hinting at their hollow power. The cast jumping into the audience cements this, proving the Golbin Gang are for the people! Still, the tiny subtitles tucked at the stage’s edge demand constant attention; for non-Korean speakers, it’s more reading than absorbing at times, and plot-heavy scenes suffer. Thankfully, the vividly expressive music and cast fill in some of the blanks.
Lee Jeong Yeon’s music and lyrics are a masterful blend of traditional Korean music with modern day genres including hip-hop and rap. There is a familiar musical structure, showcasing chorus numbers, ‘I want’ songs, and a sweeping finale; yet traditional Korean instruments and sijo proudly show its cultural origin. The music is very clever, connecting periods of varying intensity (including some very funny moments) with ease and flair. Kim Eun Chong’s choreography blends seamless with this, again mixing modern styles such as hip hop, street and acrobatics. The lack of movement in the court scenes highlights how lifeless the regime is.
For a ‘concert’, this production is pretty much fully staged! The beautiful lighting design (Lee Woo Hyung) adds an artful layer of storytelling, including wide diagonal spots, calming greens, colour pops and fan shapes. I especially love the dramatic closes to a single diagonal spot – simple yet striking. The sumptuous hanbok-inspired costumes situate us historically while retaining a modern flair. The sound design (Kwon Do Kyung) maintains the energy and the minimalist set design keeps the focus on the action.
The cast is stunning. Their “heung” shines through with passion and panache, complemented by spectacular vocals and dancing. Lim Hyun Soo’s Hongguk is a particular highlight, with a rich baritone voice and magnetic stage presence both striving and sincere. Yang Hee Jun’s Dan transforms from cocky youth to commanding force with every note of his powerhouse tenor. Kim Soo Ha’s Jin balances fierceness with fallibility, her tender vocals soaring into a defiant belt, heightening the tension of her situation.
‘Swag Age in Concert’ is a musical and cultural experience worth catching if it graces London’s stages again. Non-Korean speaking audiences might miss out on its full gravity, but the energy and artistry more than deliver in this fiery, defiant, emotionally charged production.
