the 60's is a hard decade to tie down musically. The difference between the music of the early 60's & late 60's is large. Many of the bands mentioned didnt release material till 69 and didnt achieve their audience base until the 70's. The particular era I enjoyed was 67-75/76 and stands apart from the two actual decades. This would include bands such as Hendrix, Joplin, Zeppelin, Pink Floyd, Allman Brothers, Guess Who, James Gang, Mountain, Free, Tull, ELP, King Crimson, Sabbath, Rooster, Grand Funk, Uriah Heep and streaches far enough to include such bands as Queen, Rush and Crack the Sky. I wasnt much on the Beatles, the Doors or the flower power, Haight-Ashbury kind of stuff. I like some of the songs but, it just wasnt my era or style.
