Green attended Leeds University, where he met the musicians with whom he would found the band Alt-J in 2007.

In 2016, Green released a solo album of electronic music entitled High Anxiety.

[2][3] The album was recorded over a span of several years while on tour with Alt-J, and reflects Green's medical problems with anxiety and major hearing loss due to Alport syndrome.

He has however added a small Chopper cymbal for the song "Pleader" used on tours after the release of Relaxer.

He also uses a small 10-inch snare as his main piece for a more electronic sound.
