Top Ten Most Powerful Albums of the 1970s

The beginnings of neoclassical and power metal, and a song from the album is pure speed metal (A Light in the Black)

This album is really a raw power!

Speed King=It Begins with a Killer Guitar Solo
Bloodsucker=A Hard Rock song with aggressive some screams...
Child in Time=A power ballad with classical music progressions, screams and a badass instrumental part!
Flight of the Rat=The riff that inspired Sweet's Set Me Free
Into the Fire=Again, a great hard rock song!
Living Wreck=Maybe the softest song from this album, but still heavy enough! I think it's half a funk rock song...
Hard Lovin' Man=An early proto speed metal riff, and possibly the second metal song after "Black Sabbath"

Only #8 because 3 songs from the album are too soft.
