The band took shape in a one-room studio in Brooklyn in 2016, in the wake of another collaboration: Abner often worked as a director and photographer with artists and bands whose music Harper produced. Following one such project, the brothers decided to blow off some creative steam, and spent the night writing and recording a track of their own. The result was “Three Thirty” — and after listening to the song the next morning, they decided to make the project official and began work on the Elizabeth EP.
Eighty Ninety's debut single "Three Thirty
" — a hook-laced, hypnotic message to a past love — was featured on Spotify playlists including Fresh Finds, New Music Friday, Pop Rising, Viral Hits and more, reaching #2 on Spotify's Global Viral Chart. Their followup EP "Elizabeth" has since garnered over 16 million streams. The EP included singles “Heartbreaker” — which also featured on Spotify’s New Music Friday and made waves on international viral charts —and “Fading”, which saw them cover the Fresh Finds playlist.
In September 2017 Eighty Ninety announced their upcoming EP "Bowery Beach Road" and released its first single, nostalgic indie-pop anthem "Your Favorite Song".
