[2] Prior to launching his solo career, Colwell worked behind the scenes in the Australian music industry, assisting Karen O with her performance of "Stop The Virgens" at the Sydney Opera House in 2012 and arranging vocals for Architecture in Helsinki.

[3] The song topped AMRAP's Metro radio chart for four consecutive weeks[4] but programmers at Triple J told Colwell, who was 25 years old at the time, that "Don't Cry Those Tears" sounded 'too old' to be played on the station.

[7] In August 2016, Colwell released When The World Explodes,[8] an EP featuring remixes of songs from Only When Flooded... by HEALTH, Fennesz, Roly Porter, Ash Koosha, Rabit and Marcus Whale.

[10] The pair reunited in January 2020 for a sold-out run of Wolf shows in London,[11] with Colwell contributing arrangements and multi-instrumental accompaniment.

"[12] BrooklynVegan called Swandream "a record loaded with lush, moody ballads and soaring anthems"[14] and Junkee crowned it "the fieriest and most beautiful album of the year so far".

[14] Guthrie's version appeared alongside remixes by Joel Amey of Wolf Alice and Australian musicians Rainbow Chan and Marcus Whale on the EP Swanlux.

[22] In September 2017, Colwell programmed and performed at Unity: the Equality Campaign concert at the Enmore Theatre in Sydney with Sarah Blasko, Killing Heidi, The Jezabels and others.
