[13] In 2015 Butterworth was part of the music project Songs of Separation, together with ten women folk musicians from Scotland and England including Eliza Carthy, Karine Polwart and Mary Macmaster.

Young is known for his virtuosic and semi-improvised performance, so when Butterworth accompanies him she may know what tune he is going to play but not how many times through, or with what variations and key changes.

She has to improvise in the moment, which she thinks makes the performance more exciting,[15][16] at the same time holding to Young's preferred harmonies, which can be quite proscriptive.

Colin Irwin in his Guardian review of Jenn and Laura-Beth's 2017 album Bound called Butterworth an "outstanding guitarist" and noted the duo's "clever, intricate, genuinely exciting and perfectly executed instrumental tunes".

[19] The partnership of Butterworth and Salter also led to the creation of Kinnaris Quintet, comprising the duo and three fiddlers, Aileen Reid, Laura Wilkie and Fiona MacAskill.

The band has an energetic driving sound, which Butterworth supports with a stomp box and various effects pedals.

[15] In 2012, Butterworth was appointed Lecturer in Practical Studies in the Traditional Music department of the Royal Conservatoire of Scotland, where she teaches guitar and ensemble.
