At 14, pre-punk, Hawkwind "Space Ritual" was absolutely my number 1. And I still listen to it now.
Ziggy Stardust (though now I probably prefer Aladdin Sane).
Pink Floyd "Wish You Were Here". (Still love it)
Hendrix "Electric Ladyland".
You could add onto those many others by Procul Harum, Carole King, Simon and Garfunkel, Fleetwood Mac, Velvet Underground, Roxy Music, Family, Lennon ... christ, loads. In fact,one of my most visited channels on youtube is The Beat Club. Brilliant memories of that era.
