I Want You (She's So Heavy)
The first traces of doom in rock music could be heard as far back as The Beatles' 1969 track "I Want You (She's So Heavy)". Black Sabbath is generally regarded as being the progenitors of doom metal. Black Sabbath's music is (in and of) itself stylistically rooted in blues, but with the deliberately doomy and loud guitar playing of Tony Iommi, and the then-uncommon dark and pessimistic lyrics and atmosphere, they set the standards of early heavy metal and inspired various doom metal bands. In the early 1970s, both Black Sabbath and Pentagram (also as side band "Bedemon") composed and performed this heavy and dark music, which would in the 1980s begin to be known and referred to as "doom metal" by subsequent musicians, critics and fans.
