Premise: SuperpinkyMandy is the debut studio album of British singer Beth Orton. Largely in the style of electronica, and produced closely with then boyfriend William Orbit, it was a limited Japan-only release, with about 5000 copies pressed. As such, it is very much sought after. Orton largely passes over the release when interviewed, citing 1996's "Trailer Park" as her first release.
Hypothesis: SuperpinkyMandy came before "Trailer Park"
