hrtz.wav is a 5-member global band formed by the top-ranking members from each position on Mnet's global band-making survival show Steelheart Club.

Their debut album The First Wave captures the moment five members, each carrying their own unique frequency, come together to create the very first 'wave' in a world that had fallen silent. A true introduction to hrtz.wav's distinct color and identity, The First Wave marks the beginning of something new.

Available in a hrtz or wav ver.
