[14] On 29 October 2020, Sultana released the fourth single "Willow Tree", and features Australian rapper Jerome Farah.

[17] In a review for AllMusic, Mark Deming stated: "Terra Firma is mostly rooted in laid-back, gentle grooves, with more room for personal introspection and ruminations on relationships and one's place in the larger world.

Sultana's vocals have gained some range and nuance since their first album, and there's a welcome sense of the artist embracing the joys of pushing the boundaries; the guitar work here is very fine but not flashy, and shares the stage with keyboards and other flavors that give the tracks a rich and varied sound.

[19] Gemma Ross of Clash said: "Terra Firma offers a much more nuanced and settled approach to Tash's ridiculously enormous musical palette, where their first album acted as a mismatch of a not-quite-yet figured out style.

Easy listening, bubbly, psych-pop-cum-soul-cum-funk and perhaps every other genre you could conjure up, Tash Sultana has come a long way from Flow State.
