Boretronix is the name of a series of obscure self-released cassette-only releases by Japanesenoise rock band Boredoms, consisting of heavily edited recordings of rehearsals and live shows. Although four releases are documented, six are reported to exist, and only the first three are proven to exist after they were made available online. All were released in extremely limited quantities.
No discographies contain information regarding Boretronix 4 or confirming the existence of 5 and 6. A Best of Boretronix compilation release was scheduled by the Ecstatic Peace! label, but has not been released yet.
