Welcome to Hell is the debut studio album by English extreme metal band Venom. It was released in December 1981, through Neat Records, at the culmination of the new wave of British heavy metal movement. The music of Welcome to Hell is described as a mix of heavy metal and speed metal, but it had a great influence on the emerging extreme metal genres of thrash, death and black metal.
The unpolished sound is a result of it being recorded in only three days. According to author Dayal Patterson, the relatively low-fidelity of Welcome to Hell inspired other Norwegian metal bands, who considered it black metal. Patterson says that Welcome to Hell and Black Metal were both the genesis for the black metal genre, with the earlier album "where it was born."
