2017–2022: Music creations and South Buyers Club
Nam continues sharing his music creations and covers on his SoundCloud account,[18] including a cover of Radiohead's "Creep", Park Hyo-shin's "Beautiful Tomorrow", and "Breath" (숨). His influences arise from artists across many genres, such as Nirvana, The Beatles, The Rolling Stones, B.B. King, and Eric Clapton. He then created a Tumblr site on January 5,[19] posting announcements and communicating with fans from time to time. On January 23, Nam started recruiting applications for his upcoming band.
On March 25, Nam, together with his rumored band, South Club, held a guerrilla show at Pet Sounds Bar in Korea. The 30-minute show was livestreamed on platforms such as Instagram, and popular China video-sharing platform Miaopai. South Club performed a total of four songs, including tracks from The Beatles and Foster the People.[20] On April 11, Nam announced that his music label "South Buyers Club" has officially been registered as of March 30.[21] On May 26, South Club released the music video for their first pre-release track "Hug Me," which was a ballad rock track.[22]
South Club's first EP 90 was released on June 27, along with music videos for the two title tracks: "Liar" and "I got the Blues.". The name of the album was inspired by the expression of freedom of youths in the 90s. It was also due to the fact that all members of the band were born after the year 1990.[23] On July 9, the band came back with their first single titled "아니 (No)".[24] After the member Yooni's departure,[25] the band's first release as a four piece was the second single "누굴 위한 노래인가요 (Who Is This Song For?)", which became available for streaming on December 5, 2017.[26]
Following their initial releases, South Club continued to produce music and expand their discography. Their second EP, titled "20", was released on June 28, 2018, followed by their third EP, "Contact Information", on October 24, 2018. The band's musical journey continued with the release of their single album "Twice (두 번)" on January 27, 2019. South Club further expanded their repertoire with singles such as "To My Friends" on March 18, 2020, and "Ride In" later on. Throughout their career, the band has consistently explored themes of youth, freedom, and personal experiences in their music, maintaining their alternative rock style with blues influences while continuing to release music and perform, adapting their sound and staying true to their rock roots.
