Fascinating cross-section of the period. I'm more of an early-mid 70's person, but some brilliant work made it from there into the late 70's, including these works from three of rock's greatest guitarists (sadly unknown today):
"Sleepy" from Gong II (featuring Allen Holdsworth) https://youtu.be/Z800qugSfA4?si=ia8U_hnw6vs_m48g
"Ice" from Camel's I Can See Your House from Here (featuring Andy Latimer--still playing today!) https://youtu.be/dEHHs3VoJ7g?si=sOE7vKzLsltCs9RH
"Dreams Wide Awake" from National Health's Of Queues and Cures, featuring Phil Miller on guitar and Dave Stewart on organ
