Null Signal is a post-industrial noise group out of the Shelf's lower levels — three musicians, two of whom have significant audio-augmentation chrome, who play shows in decommissioned pump stations and condemned transit hubs. This shirt was sold at their 2199 'Meridian Loop' tour, which consisted of seven illegal shows across five Tier 1 and 2 venues. The design is stark: a black shirt with a white interference-pattern graphic that looks like a corrupted audio waveform across the chest. On the back, the seven venue names, three of which are listed only by grid coordinate because they have no official name.

The shirt itself is basic synth-cotton — thin, slightly rough, fades fast. That's part of it. The fading is correct. A Null Signal tee that looks new is suspicious; a Null Signal tee that's been through sixty washes and has a small hole at the collar is the real artifact. Bootlegs exist, but the bootlegs fade differently.
