How very 'meta'. Breton's music video for 15X features them actually making (as in manufacturing rather than recording) their forthcoming Sharing Notes EP, including the packaging. In fact, since the release is limited to 50 numbered copies, if you get number one then that is the one being made in the video. The release includes a printed circuit board which can apparently be built into a synth. Nice.
The song itself is math rock in a similar vein to the Battles but a bit spikier. But don't take our word for it - check it out above.
