The Night ATEEZ Covered BTS in Front of BTS: The 2019 MAMA Stage, Explained
Spotlight is our series on the music videos and performances that show why the world fell for K-pop. Earlier in the series we dissected music videos; today we’re back on stage — with the awards-show slot that turned a rookie group into an industry conversation.
Awards-show stages are K-pop’s proving ground, and MAMA is the biggest of them. On December 4, 2019, at Nagoya Dome, the lineup ran through BTS, TWICE, SEVENTEEN, GOT7, and MONSTA X — and, in the slot MAMA reserves for newcomers, a group that had debuted barely thirteen months earlier as the first group KQ Entertainment raised from its own trainees: ATEEZ.
Round one: the red carpet
ATEEZ actually performed twice that night. The pre-show got a remixed run of “Say My Name” and “HALA HALA” — the two Treasure-era songs that had built their international fanbase — compressed into a five-minute opening argument.
Round two: covering the canon, in front of the canon
The main-show stage is the one fans still talk about. MAMA’s rookie programming that year had newcomers weave covers of established K-pop hits into their own singles, and ATEEZ’s picks were audacious: their own “WONDERLAND” rebuilt around BTS’s “Blood Sweat & Tears,” SHINee’s “View,” and miss A’s “Goodbye Baby” — three eras of the K-pop songbook, performed in all-white with a small army of backup dancers, with BTS watching from the audience.
The staging details did the talking: Wooyoung rising from the floor with a hand motion to open the “Blood Sweat & Tears” section, and Mingi baring his chest for the finale. And because this is MAMA, the reaction cameras found the one table that mattered: Jimin and J-Hope smiling through the cover, J-Hope throwing a thumbs up, RM nodding along — a rookie group getting an on-camera nod of approval from the group they were covering.
The receipts
The performance wasn’t just a fandom moment. The Bias List put the ONEUS–ATEEZ rookie block fourth in its round-up of the week’s six best award-show performances, calling ATEEZ’s cover choices “especially inspired.” The same night, ATEEZ collected a Worldwide Fans’ Choice Top 10 award — sharing the category with BTS, SEVENTEEN, and TWICE in their second year of existence.
Honest ledger, though: Best New Male Artist went to TXT that night, and even the glowing coverage framed ATEEZ’s stage as the case for what the trophy didn’t say. The performance was the argument; the awards caught up later.
The homework behind it
What makes this stage a satisfying deep-dive is that the preparation is on the record. KQ published the full performance practice video — which, as of July 2026, has out-viewed the stage uploads themselves at 2.8 million plays — and Mnet’s cameras followed the group’s first-MAMA nerves for a two-part docuseries, MY FIRST MAMA. Watch the practice room version back to back with the M2 fancam and you can see exactly how much of the “spontaneous” stage was drilled down to the frame.
Why this stage matters now
Rookie stages are bets on a future, and this one paid out in full: the years that followed brought Coachella and three Billboard 200 No. 1s — we traced that whole voyage in our ATEEZ universe guide. But the 2019 MAMA stage is where the pattern first showed on the biggest screen available: a group from a small company treating an awards-show slot like the only shot they’d get.
