Black Sabbath, an English rock band formed in Birmingham in 1968, is widely recognized as the creators of the heavy metal genre.

Their original lineup consisted of guitarist Tony Iommi, drummer Bill Ward, bassist Geezer Butler, and vocalist Ozzy Osbourne.

The band distinguished themselves through occult themes, horror-inspired lyrics, and the use of down-tuned guitars.

Their first three albums, Black Sabbath (1970), Paranoid (1970), and Master of Reality (1971), were not only commercially successful but are also considered pioneering albums in the development of heavy metal.

In particular, Paranoid is considered one of the greatest and most influential heavy metal albums of all time, defining the sound and style of the genre.

Their Mark II lineup, consisting of Ian Gillan (vocals), Ritchie Blackmore (guitar), Roger Glover (bass), Jon Lord (keyboards), and Ian Paice (drums), cemented their powerful, classic sound.

The albums In Rock (1970) and Machine Head (1972) were milestones in rock history, with "Smoke on the Water" becoming an iconic song featuring a memorable riff and a powerful sound.

Deep Purple has also been called part of the "unholy trinity" of British hard rock and heavy metal.

In 1975, they were inscribed in the Guinness Book of World Records as the "loudest band in the world" for their 1972 concert at London's Rainbow Theatre.

Led Zeppelin was an English rock band formed in London in 1968, consisting of vocalist Robert Plant, guitarist Jimmy Page, bassist-keyboardist John Paul Jones, and drummer John Bonham.

With their heavy, guitar-driven sound, influenced by blues and folk music, Led Zeppelin is considered a pioneer of hard rock and heavy metal.

Page's ferocious guitar riffs, Plant's soaring vocals, and Bonham's thunderous drumming became their trademarks.

Albums such as Led Zeppelin I (1969), Led Zeppelin II (1969), and their untitled fourth album (Led Zeppelin IV, 1971) are considered classics in the genre.

Some have even stated that Led Zeppelin II was "the musical starting point for heavy metal.

"Led Zeppelin is also part of the "unholy trinity" of British hard rock and heavy metal.

Formed in 1966, Cream was an English power trio consisting of drummer Ginger Baker, bassist and vocalist Jack Bruce, and guitarist and vocalist Eric Clapton.

Cream is considered the first rock power trio and laid the foundation for heavy metal, inspiring later generations of bands like Black Sabbath and Van Halen.

Cream's use of amplified distortion and powerful riffs laid the foundation for many later heavy metal bands.

Eric Clapton himself once stated, "I think we were one of the first heavy metal bands without even realizing it," adding that Led Zeppelin filled the void after Cream's breakup.

Ginger Baker's double bass drumming was also a key precursor to this technique in heavy metal.

The Who, while not universally recognized as the creators of heavy metal like Black Sabbath, have a significant claim to and influence on the development of the genre.

Pete Townshend, The Who's guitarist, explicitly stated that his band "sort of invented heavy metal" with their live album, Live At Leeds, released in 1970.

He claimed that many bands, most notably Led Zeppelin, imitated their style, featuring "heavy drums, heavy bass, heavy lead guitar."

Several sources also acknowledge The Who's influence, with the song "Boris the Spider" being cited as an influential "metal" song.
