 ==heavy metal first please== 
 ""The exact order and wording by editor consensus is: Hard rock, heavy metal"" 

 The most sources point to Led Zeppelin as one of the pioneers of heavy metal. So why hard rock appears in front first? The Allmusic itself in its definition of heavy metal points Led Zeppelin as the first metal band ([Allmusic http://allmusic.com/cg/amg.dll?p=amg&sql;=77:655] says: Arguably the first true metal band, however, was Led Zeppelin. Initially, Zep played blues tunes heavier and louder than anyone ever had, and soon created an epic, textured brand of heavy rock that drew from many musical sources.). On the main page of Led Zeppelin at [Allmusic http://allmusic.com/cg/amg.dll?p=amg&sql;=11:wifexqe5ldde~T1], which reads: ""Led Zeppelin was the definitive heavy metal band. It wasn't just their crushingly loud interpretation of the blues  it was how they incorporated mythology, mysticism, and a variety of other genres (most notably world music and British folk)  into their sound. Led Zeppelin had mystique. They rarely gave interviews, since the music press detested the band. Consequently, the only connection the audience had with the band was through the records and the concerts. More than any other band, Led Zeppelin established the concept of album-oriented rock, refusing to release popular songs from their albums as singles. In doing so, they established the dominant format for heavy metal, as well as the genre's actual sound.""  

 We Have the film Some Kind of Monster Metallica, where the Father of Lars Ulrich explains the rise of metal in England with Led Zeppelin to the days of Metallica.  

 We are hit with the audience and critical Metal: the headbanguer's Journey (2005) showing that the hard rock bands have emerged since the early metal. The film also shows the Led Zeppelin as early metal and not hard rock.

 Judas Priest Biography by Stephen Thomas Erlewine & Greg Prato  
 Judas Priest was one of the most influential heavy metal bands of the '70s, spearheading the New Wave of British Heavy Metal late in the decade. Decked out in leather and chains, the band fused the gothic doom of Black Sabbath with the riffs and speed of Led Zeppelin, as well as adding a vicious two-lead guitar attack; in doing so, they set the pace for much popular heavy metal from 1975 until 1985, as well as laying the groundwork for the speed and death metal of the '80s.

 NWOBHM: The New Wave of British Heavy Metal re-energized heavy metal in the late '70s and early '80s. By the close of the '70s, heavy metal had stagnated, with its biggest stars (Led Zeppelin, Black Sabbath) either breaking away from the genre or sinking in their own indulgence, while many of its midlevel artists were simply undistinguished, churning out bluesy hard-rock riffs. The NWOBHM kicked out all of the blues, sped up the tempo, and toughened up the sound, leaving just a mean, tough, fast, hard metallic core. It didn't make any attempts to win a wide audience — it was pure metal, made for metal fans. Perhaps that's the reason why it's at the foundation of a
