Master's Hammer were a black metal band from the Czech Republic, founded by Franta Storm and Vlastimil Voral. They were founded in 1983 and produced several demos, before releasing their debut album Ritual in 1990. Two years later they completed an operetta titled Jilemnice Occultist (often misspelt as Filemnice Occultist due to a typo on the booklet). Their final album was a drift away from the previous work incorporating many styles outside the metal genre. Most if not all of their lyrics are written in the Czech language.
