Lost Wisdom is the second studio album by Mount Eerie, with Canadian musicians Julie Doiron and Frederick Squire.

[2] She was a member of Eric's Trip, an indie noise pop band from the early 1990s, and has since recorded numerous solo albums.

Doiron and Squire had a few days between a recent tour and an upcoming recording session in Olympia, Washington,[2] and made a surprise visit to Phil Elverum in Anacortes.

[4] The track "Voice in Headphones" on this album reprises the chorus from Björk's song "Undo", over a different verse.

Due to the impromptu nature of the recording session Elverum didn't intend to release the album.

[4] The album was however released on October 7 on LP and CD, the vinyl version included a double-sided jumbo poster.

[7] Heather Phares of AllMusic wrote that despite the fast time to create the album "its simplicity and immediacy sound intimate instead of tossed off" she also complimented the chemistry between Elverum and Doiron writing that "He and Doiron sound completely natural yet haunting trading verses".
