A limited edition longsleeve designed by Dataset Clothing in collaboration with Portland-based bass music producer EPROM and Tokyo culture platform FACTRY.

The garment was built around three elements: a front illustration developed closely with EPROM, an ASCII-style logo on the sleeve, and a satin triangle label on the hem uniting all three collaborators. The design language drew from EPROM's machine-influenced aesthetic and the EPROM memory chip his name derives from.

The sleeve artwork contained a hidden code, never advertised. A dedicated fan eventually cracked it, leading to a private URL where an exclusive live EPROM recording could be downloaded. No announcement, no marketing. A quiet reward for whoever cared enough to look.

Released in limited quantities through FACTRY's platforms in Japan and internationally.

The Hidden Code Embedded within the ASCII artwork on the sleeve was a hidden code — invisible to the casual eye, legible only to those who knew to look. No announcement was made. No hint was dropped. The code simply existed, waiting.

Eventually, someone in EPROM's fanbase found it. The code resolved to a private URL, and the URL led to a page where an exclusive live recording of EPROM's music could be downloaded — a direct, unmediated transaction between artist and the most dedicated corner of his audience.

It was a design decision rooted in a specific understanding of fan culture: that the people who care most are also the ones most likely to scrutinize every detail. The reward wasn't manufactured scarcity or a marketing hook. It was a genuine gift, hidden in plain sight, for whoever cared enough to find it.

Distribution The shirt was released in limited quantities through FACTRY's platforms — domestically through factry.jp and internationally through factry.tokyo — positioning it as a Tokyo-anchored release with a global reach into the bass music community.
