Cut Up the Border is a 2020 live album by English guitarist and composer Fred Frith, German film maker Nicolas Humbert [fr] and French sound artist Marc Parisotto.

[1] The result was presented at Babylon, a Berlin cinema in Mitte on 17 January 2019 with Frith improvising live over the sound piece.

[4][5] In January 2020, RogueArt released the Berlin cinema recording of the radio play on CD entitled Cut Up the Border and credited it to Fred Frith, Nicolas Humbert and Marc Parisotto.

[7] Commenting on Frith's live participation at the Berlin cinema presentation of Cut Up the Border in January 2019, Thomas Mauch saw it as an opportunity for the musician to have a conversation with his past in the sound collage.

Mauch stated that Frith's contribution to music and improvisation over the years, as demonstrated in Step Across the Border, is of paramount importance, but here he appeared alone and "a little lost" on the stage.
