He was previously a member of The Suicide Machines, Telegraph, Gyga, Thoughts of Ionesco, Remainder, Walls of Jericho, The Exceptions and Broken Spoke.

This material, recorded by Grant (with help from Saves the Day guitarist Arun Bali) is described as "Electro-Funk" and features a cover of an unreleased Prince track ("Electric Intercourse"), and two original compositions.

It was mixed by The Swellers frontman Nick Diener at Oneder Studios in Michigan who also played bass and guitar and sung on Dan's songs.

In June 2023, Grant announced his departure from Alkaline Trio, citing mental health and a desire to pursue production and graphic design as factors.

Though he was replaced by drummer Atom Willard following his announcement, his final appearance was on the band's 2024 album Blood, Hair, and Eyeballs, having completed his drumming duties before his departure.
