[4][5] Dexter Fabay, turntablist and keyboardist for the band, brainstormed the idea for "Frontier Psychiatrist", and his scratching is heard prominently on the track.

[2] The prominent orchestral sample heard throughout the track is sourced from a recording by the Enoch Light Singers of the 1968 composition "My Way of Life", originally composed by Bert Kaempfert, Herbert Rehbein and Carl Sigman.

[10] The closing mariachi band plays "El Negro Zumbón", first performed by Flo Sandon's, who doubles Silvana Mangano in the 1951 movie Anna.

[13] Christine Hsieh of PopMatters wrote: "Most impressively, though, is the way the Avalanches make things like whinnying horses and spoken word sound kooky and fresh instead of recycled and stale."

[14] Matthew Horton, writing for the book 1001 Songs You Must Hear Before You Die, described it as "the album [Since I Left You] in microcosm—busy, daft, composed of countless unconnected parts, yet somehow entirely natural as a whole.

[15] The "Frontier Psychiatrist" music video, directed by Tom Kuntz and Mike Maguire,[3][16] features characters re-enacting and musicians playing elements of the track, including vocal samples, violins, horns, serpents and drums.

[16] An alternative video was made, featuring actors acting out the 'dialogue' of the track in various scenes, including a psychiatrist's office and "Dexter's" bedroom.
