Master's Hammer were formed in mid 80's in Prague, Czech Republic. Prior to getting a contract from the Czech label Monitor Records, the band release three demos of black metal in Bathory vein with dark and evil atmosphere, which wins them a lot of fame with the uderground metalheads.
The fall of repressive communist regime in the end of 1989 finally brings about the chance to release the heavily supported metal music officially, an opportunity first taken by a new record label Monitor who invite Master's Hammer to participate on their first metal sampler called Ultrametal with two songs: "Zapálili jsme onen svìt" and "Géniové ...", the latter also supported by a video clip.
The debut record entitled Ritual follows soon presenting another portion of original conception of black metal with a slight avantgarde classical touch, an element ever so praised in the band's creation. Another promo video is recorded, however this is the last cooperation with Monitor who turn their back on metal later on.
Underground connections gain the band the chance to release (now very rare) 2 track EP under Poserslaughter records in the following year. The form of presenting the songs on this record already suggests another excellent contribution in developping the genre - a black metal operetta with original libretto by the band's mastermind Franta Storm. The Jilemnice Occultist, originally presented as a demo recording on tapes attracts the interest of French black metal oriented Osmose Productions and the CD release follows shortly after.
The contract with Osmose helps the band gain interest from the fans outside Czech Republic which ensues in the label's re-release of their debut, by then hardly available outside the band's country.
The band's activities by then, however, almost cease, with only Frank Storm and Vlasta Voral remaining of the original line-up, Necrocock founding his gothic doom rock band Kaviar Kavalier. The remaining two begin more experimental way preparing yet another album to be released under the cult monicker. The material on Slagry has nothing to do with black metal as the band used to play it, though. Rather, we find a lot of experimenting with samples, computers and techno themes. Rumours say the material was put together to discredit Herve from Osmose, for what reason I know not.
Further activities of the members are not known. In 2000, though, Czech Redblack label compile 13 cover songs from the best Czech bands to re lease A Tribute to Master's Hammer CD with an original foreword from Franta Storm.
