As part of a promotional video for Xenoblade Chronicles 3D, this track was rearranged by Tomori Kudo.

The piece was performed on both day 1 and day 2 of Nintendo Game Music Live!, a series of performances of Nintendo music by rock band and big band as part of the Nintendo Switch Experience event on 14/15 January 2017. In both performances, the piece was given a substantially different structure, including entirely new sections.
