While the timing was pushed back, due to several health issues, and touring delays, Sultana gradually released sneak peeks of the album recording process via their social media channels.

On 21 June 2018, Sultana premiered the song "Salvation" live on triple j Breakfast with Ben and Liam, and announced the forthcoming release of their first studio album, Flow State.

In an April 2018 interview with online Spanish blog Indierocks, Sultana spoke about the influence behind the name Flow State and said "it's the term to refer to when you access a part of your mind known as your being, and you find something you are passionate about.

[13] Ryan Bray of Consequence of Sound gave the album a B+, commenting "This is great pop music with an edge, a record full of good vibes and bad attitude, that somehow manages to work everything out splendidly.

"[16] Maura Johnston of Rolling Stone awarded the album four of five stars, stating that "After years of being a festival and YouTube sensation, Sultana's thrown down the gauntlet forcefully.

"[19] For Beat Magazine, Nathan Gunn rated the album 9/10 and commented "This record (Flow State) represents a quantum leap -- a major milestone in Sultana's seemingly short career.

[14] Mikey Cahill of the Herald Sun rated the album four of five stars, commenting "I thought she’d boxed herself in on the eager Jungle EP.

"[18] In a more critical review, Rachel Aroesti of The Guardian awarded Flow State 3 of 5 stars, commenting "Lacking any particularly memorable melodies, it is expansive and mellow, recalling 90s singer-songwriter fare with added R&B flavours, spacey instrumentation and psychedelic guitar wigouts.".
