On the 8th, a debut media showcase for hrtz.wav's mini 1st album "The First Wave" was held at the Oil Tank Culture Park performance hall in Seongsan-dong, Mapo-gu, Seoul.

"The First Wave" is an album that captures the first wave of the global, all-round band hrtz.wav formed through Mnet's survival show "Steel Heart Club." It includes the title track "NINETEEN," member Rian and Dane's self-written song "Clumsy," and a total of six tracks: "Dream," "Highlight," "I AM SO FINE," and "Our Story (Close To Me)."
