"Underflow" is a song by Australian singer Emma Louise, released on 7 November 2015 as the lead single from Emma Louise's second studio album Supercry.

Emma Louise said "I wrote 'Underflow' about a feeling of knowing that a change is about to come.

"[1] The song placed second at the 2016 Vanda & Young Global Songwriting Competition.

To collaborate with an artist who has such a clear direction in terms of her aesthetic and image was really cool and proved such a smooth process.

[5] Lauren Ziegler from Indie Shuffle called the song "stunning" and "heartbreaking" saying "The instrumental layers see delicate, muffled piano trickles meeting an ambient, emotive soundscape.
