After announcing Optimist with lead single "A Concert Six Months From Now" last month, Finneas has delivered "The 90s", which sees him dabble with Autotune and glitchy electronica, and will appear on his debut album alongside last year's "What They’ll Say About Us".

As well as preparing to release Optimist, Finneas starred in the video for James Blake's "Say What You Will", collaborated with his superstar sister Billie Eilish on her recent second album Happier Than Ever, featured on Ashe's "Till Forever Falls Apart", and co-produced girl in red's "Serotonin" song.
