Someone Else's Déjà Vu is the third full-length studio album by American alternative indie rock band Son, Ambulance.

[2] Andrew Earles of Spin wrote: "Omaha-based multi-instrumentalist Joe Knapp spent three years making Someone Else's Déjà Vu, and the album is another reminder that lush studio-reliant soft and prog rock of the late '70s can still offer legitimate inspiration".

[6] In mixed reviews, Ian Cohen of Pitchfork found that the album "would've benefitted from Knapp making a stronger claim of ownership to his lofty visions".

Yet that's not to say this is a bad record per se, it's just that Knapp's whole Son, Ambulance project has a good few obvious clangers dragging it down".

[3] Bob Marshall of Tiny Mix Tapes called "Knapp and Koster’s experiment was more failure than success".
