[7] Roche recalled how "daunting" it was to learn the song as a teenage guitarist: "My aunt Terre taught it to me and I remember the overwhelming and seemingly impossible task of switching to a C chord in the chorus as a new player.

"Do You Love an Apple" is credited Kevin Burke, Tríona Ní Dhomhnaill, Mícheál Ó Domhnaill, Paddy Keenan, Dónal Lunny, and Matt Molloy.

The song "El Condor Pasa" premiered on Speakeasy, a blog affiliated with The Wall Street Journal, via SoundCloud, on October 7, 2015.

[3][17] CBC Music's Melody Lau opined, "Wainwright and Roche display a familiarity and ease around each track, delivering each refrain with a palpable sentiment".

"[12] Jude Rogers of The Guardian called the album a "lovely, twilit thing" and the duo's London performance "powerful because the sisters' different voices create a strange magic together.

She said "Opener Prairie Lullaby" was "equally lovely" and the songs "Runs in the Family", "All the Pretty Little Horses", and "End of the Rainbow" were a "rare treat".

[10] The Wall Street Journal's Eric Danton said the sisters' voices, specifically on "El Condor Pasa", "[interlock] so tightly it feels instinctual".
