Andy Morin was born on May 16, 1986. He first met Zach Hill in 2009 while collaborating with Nathan Williams on the aborted Wavves album Babes, and would work with Hill again on his second solo album Face Tat, both of whom were recorded at Morin's personal studio in Sacramento, California. Shortly following Hill and MC Ride forming Death Grips, Morin was recruited to produce the band, initially going under the name "Flatlander" on early releases such as Exmilitary. Following his recruitment, he worked as the band's producer and engineer, as well as its keyboardist. In 2015, Morin and Hill formed the band The I.L.Y's, releasing three studio albums before going on hiatus in 2017. Upon the reformation of Hill's previous band Nervous Cop, Morin joined the band and performed on their 2017 self-titled EP. In 2022, Morin founded the record label A2B2, with their first release being Death Insurance's I'm In Your Walls. In 2024, Morin co-produced the album Perfect Answer by Evanora Unlimited, The next year, he co-produced the single "Shark Brain / Dolphin" by Eartheater and Shygirl.
In 2025, a leaked message between Morin and a fan, in which Morin stated that the band was over, fueled discussion that Death Grips may have broken up. However, later that year, a social media post by the band confirmed they were still active. The post was only signed by Hill and Ride. Additionally, later in 2025, the band would announce on social media that they were working on a new studio album, again with no signature from Morin.
