Yeonjun's momentum from his chart-dominating solo project "NO LABELS: PART 02" just hit another high note. The TXT member will make history as the first Korean artist to perform at iHeartRadio's Z100 Summer Bash, taking the stage at New York's Hudson Yards. The announcement came July 13 local time, placing Yeonjun alongside major artists like Charlie Puth and Bella Kay on this year's lineup.

The performance caps off a remarkable stretch for the 20-year-old. His solo release earlier this month set 2026's highest opening-day sales record among Korean soloists—a significant achievement that underscored his growing solo presence in the industry. Now, with this U.S. festival booking, Yeonjun is expanding that reach internationally.

The timing aligns perfectly with another TXT win. On July 14, the group's "Deja Vu" music video crossed 100 million views on YouTube, becoming their 10th MV to reach the milestone. The track took approximately two years, three months, and 13 days to achieve the feat, reflecting the sustained interest in TXT's catalog.

"Deja Vu" stands as a testament to TXT's consistent performance across their releases. With 10 videos now in the 100-million-view club, the group continues solidifying their position as one of the industry's most-watched acts. The song's longevity also highlights how TXT's releases maintain relevance well beyond their initial release windows.

For Yeonjun specifically, the Z100 Summer Bash appearance represents a notable step in bridging K-pop and mainstream U.S. music festivals. The event, held at one of New York's most prominent outdoor venues, typically draws significant crowds and media attention. As the first Korean artist on the lineup, Yeonjun's presence signals growing recognition of K-pop talent in American music spaces—a shift that reflects both his individual appeal and TXT's broader cultural impact.

With a record-setting solo album behind him and a major U.S. festival performance ahead, Yeonjun is having quite the summer.
