Palimpsest is the fifth studio album by Canadian progressive metal band Protest the Hero released on June 18, 2020 through Spinefarm Records.

Palimpsest marks the band's first studio record since 2013's Volition, and their first new material since 2016's Pacific Myth EP.

The breakneck leads and spastic riffing of Kezia and Fortress have been refined and molded to better suit an older, wiser band.

"[8] Reviewer Andy Synn of No Clean Singing said in an unrated review, "In simple terms, Palimpsest is the sound of a band renewed and reinvigorated, combining the epic vibe of Fortress (still, for many, the band's magnum opus), with the more lithe and limber, shoot-for-the-moon, approach of their debut album, Kezia".

Synn concluded, "That being said, don't go thinking that this new record is simply a throwback to the group's early years (both musically and thematically nothing could be further from the truth), as it definitely incorporates all the lessons which they learned making Scurrilous and Volition too, as well as some unexpected new tricks and twists.
