It wasn't just the big name acts in the 60's that influenced things profoundly, everybody did something of note. The Kinks pioneered guitar overdrive by daisy-chaining amps, The Creation introduced bow-playing of electric guitars, Booker T and the MGs along with the Animals pioneered organ use in rock, the seeds of heavy metal were planted by the likes of Black Sabbath, Zeppelin, Steppenwolf, and Cream, the Byrds took from Dylan and laid the foundations for later bands like Tom Petty and the Heartbreakers and the Eagles...
Not to mention the fact that musically, Jimi Hendrix, Janis Joplin and others effectively shattered preconceptions about what a musical artist could be.
