Addendum is the fifth studio album by American musician John Maus, released on April 20, 2018.

"[4] Accordingly, the songs on Addendum were made in a more "carefree" manner than Screen Memories and are most resemblant of his usual style.

[5] Addendum was first issued as a bonus vinyl disc on a career retrospective box set.

[8] Pitchfork reviewer Evan Rytlewski wrote, "Maus has made more profound and mysterious records, but never one that has taken this much delight in its own ridiculousness.

"[8] All tracks are written by John Maus except "Privacy", by Ariel Pink, and "Drinking Song", by Oswald von Wolkenstein (originally titled "Her wiert uns dürstet also sere")Notes
