Mindless Sinner began as Purple Haze in 1981. They changed their name to Genocide after singer Christer Göransson joined the band later that year, and by August of 1983, the had reached their final moniker. They recorded a four-track demo entitled Master Of Evil, consisting of: the title track, "Broken Freedom," "Key Of Fortune," and "Screaming For Mercy". This attracted Swedish label Fingerprint Records, who released the NWOBHM-inspired material as a mini-album in January of 1984, but with an awful cover and a typo in the band name that incorrectly pluralized sinner. By then, the line-up of the band was Anders Karlsson (bass), Magnus Danneblad (guitar), Jerker Edman (guitar), Tommy Johansson (drums) and Christer Göransson (vocals). In addition to the four tracks of the original release, this High Roller Records reissue pressing also contains the five songs off the band's first demo tape from early 1983. All nine tracks were mastered by Patrick W. Engel at his Temple Of Disharmony and cutting was done by SST Germany on Neumann machines for maximum quality on all levels. This is the ultimate audiophile re-issue of this Swedish metal classic.
