for accepting a track was only three days. The only song the band had completed in any shape or form was "Vow". After Volume was released in December 1994, "Vow" began to receive radio airplay from Radio 1 DJs Steve Lamacq, John Peel and Johnnie Walker, and record stores in the United Kingdom began to receive requests for a single that didn't yet exist. Garbage were still putting the finishing touches to their debut set, as well as extra tracks such as "Subhuman", which was still three months away from release. In the United Kingdom, the terms of the licensing deal regarding the inclusion of "Vow" on Volume meant that the track could only be released on a limited basis. "Vow" was issued in a 1,000 copy limited edition 7" vinyl format packaged in an aluminium sleeve, which was designed by O'Shea along with the aluminium sleeve for "Vow". The single sold out in one day. Mushroom later licensed the single out to BMG who fully issued "Vow" in Europe, and to White Records, who released "Vow" in Australia and New Zealand in a limited edition format packaged in an embossed rubber wallet. "Subhuman" was released as the "Vow" b-side on both labels. "Subhuman" release Mushroom's plan for releasing "Vow" in the limited metal sleeve had been to create an early buzz about the band and "Vow" by word-of-mouth, rather than by retail impact. For the follow-up, the label were concerned with maintaining the interest of the record buyers, as well as attracting interest from record chains. Mushroom manufactured advance discs to promote a re-release of "Vow" in the United Kingdom, but later decided to alter the single, so that the international b-side, "Subhuman", would be the title track. The label felt that "Subhuman" was a "strong single.. to release in its own right". "Subhuman" was to be a limited release as well, but manufactured in greater quantities to enable a greater retail impact than the first. Mushroom re-serviced the single to the media as a cassette featuring "Subhuman", "#1 Crush" (an album out-take) and "Vow". Garbage requested that their initial singles were to be packaged with a "high-tech, design-led approach", which led to the manufacture of the aluminium sleeve for "Vow". To follow it up, Mushroom's product manager originally wanted to create the sleeve for "Subhuman" from neoprene. Instead, he sourced a black plasticised rubber from a company in
