Celtic Frost

Celtic Frost () was a Swiss extreme metal band from Zürich. Their early work had a strong influence on the development of extreme metal, especially the death, black and doom metal genres, and they are noted for their avant-garde approach to music. Guitarist and vocalist Thomas Gabriel Fischer and bassist Martin Eric Ain formed Celtic Frost in June 1984 after disbanding their previous band, Hellhammer. Celtic Frost's debut record, Morbid Tales, was released later that year.
