Master's Hammer are an occult black metal band from the Czech Republic, founded by Franta Storm. They were founded in 1987 and produced several demos, before releasing their debut album Ritual in 1991. A year later they completed Jilemnice Occultist - the first black metal operreta. Their 1995 album Šlágry was a drift away from the previous work incorporating many styles outside the metal genre. All of their lyrics are written in the Czech language. After a long hiatus, the band has reformed. The new album Mantras was released in late 2009.
