Check out how this Spanish Wikipedia entry reads via Google translation. The entry is entitled “Gradual Rock.” And I quote:
The gradual rock is a ambitious person, eclectic and many times huge music style rock that appeared mainly in the ends of the decade of 1960 in England, reaching the peak of its popularity in the principle of the decade of 1970, but that until today it continues to be heard.
Man. Why have I not been listening to gradual rock all these years? Punk rock, hard rock, art rock, soft rock, they got nothing on the “many times huge music style rock” that is Gradual Rock!
