In 2021's Fuji Rock Festival '21, Yoshinori Sunahara and LEO Imai, performing as a special lineup of METAFIVE, welcomed support members Kenichi Shirane (Dr) from GREAT3 and Seiichi Nagai (G) from Soutaiseiriron, and launched activities under a new group name TESTSET (Test Set). On August 12, they digitally released their first recording, EP1 TSTST, and have delivered stunning performances at festivals nationwide, including SONICMANIA and Asagiri JAM. They will hold TESTSET's first Billboard Live show. It promises to be a rare night where you can thoroughly savor the four's meticulous sound production and seasoned live performance, unlike anything they've done at previous festival venues or in live houses.

As a special guest to color the night, Tachibana Hajime—musician/graphic designer/poet, leader and frontman of the techno-pop group Plastics and active in projects such as Plastics solo, Hm (Harmainer), Hm REAL FISH, and Tachibana Hajime (solo)—has been confirmed to appear! What kind of chemistry will unfold on the Billboard Live stage, their first collaboration? Please look forward to it.
