The roots of Doom Metal are considered to have been planted in the early 70s work of Black Sabbath. In the early and mid-80s, European artists like Witchfinder General and Candlemass adopted the Doom sound as a full fledged genre unto itself, as well as American acts like Saint Vitus, Trouble and Pentagram. Their style of thick and depressive Doom remained the standard until the early 90s, when newcomers such as My Dying Bride, Cathedral, Electric Wizard, and many others began to experiment in melding Doom with several other Metal subgenres. less
