Morbid Tales is the debut album by the Swiss extreme metal band, Celtic Frost. It was released in November 1984. It was originally released in Europe as a six-track mini-album. However, the first American release by Enigma/Metal Blade added two tracks, making Morbid Tales an LP. Morbid Tales had a major influence on the then-developing death metal and black metal genres. It included elements that were adopted by the pioneers of both styles.
