In December 2015 while on tour with August Burns Red, vocalist Keith Buckley left due to a life-threatening emergency with his 7-month pregnant wife and unborn daughter. It was during this time and the subsequent hospital stays that Buckley wrote a vast majority of lyrics for a new album while awaiting their clean bill of health and recovery. On September 23, 2016 the band released "Low Teens" to universal critical acclaim. The band spent the next 2 years touring with the likes of Knocked Loose, Harm's Way, Fall Out Boy, Taking Back Sunday, '68, Motionless In White, Turnstile and Machine Gun Kelly in support of the album. In September 2017, Daniel Davison parted ways with the band citing exhaustion from touring. He was replaced by Clayton "Goose" Holyoak of Fear Before The March Of Flames and coincidentally from being a replacement for Davison once before in Norma Jean. Holyoak was subsequently replaced in Norma Jean by former ETID drummer Ryan Leger. On June 21, 2018, the band embarked on the final run of the Vans Warped Tour. In October 2018, the band announced that they will embark on one last tour in support of Low Teens with Turnstile, Angel Du$t and Vein before taking time off to begin writing their ninth record. On December 15, 2018, the band was honored by their native Buffalo, for their musical accomplishments and advocacy for the city, with an annual holiday on December 15 named after the band. The band revealed in an interview they all have to share their ETID Day plaque between them
