In 66 and 67 bands like Cream, Hendrix, Amboy Dukes, The Doors, Vanilla Fudge, The Who and even The Kinks, The Beatles and The Rolling Stones were already delivering some heavy stuff!
So by 68 the hard, heavy, plodding, fuzzy sound was well established, and it really was the year "heavy rock" took off and this was evident everywhere when everyone and his dog kicked in with some proper and really good heavy albums. Then, the fantastic well known releases of 69 and 70 by some of the best known bands (Sabbath, Zeppelin,Purple, Cooper, MC5) cemented the sound forever.
