Personal opinion on some early rock albums/bands/movies for our young one:
1) The Who was a great band, Tommy was a meh movie but good album, you should listen to much Who
2) The Beatles was a great band, Sgt Pepper was a meh movie but great album, you should listen to much Beatles
3) Pink Floyd was a great band, The Wall was a kinda ok movie and is a great album, and you should listen to much Floyd
If you want to know what everyone was smoking, listen to the original 1969 Woodstock album and catch some of that footage.
I grew up in the 70's/80's and loved 60's/70's music.
Enjoy.
