Hawkwind is AWESOME!Im going to go out on a limb and say that you two are fans of Can as well?
I was born in 1967,and I lived on Haight st from 1968-70.My dad was roadie for Quicksilver Messenger Service.So I grew up around that scene,all though I dont remember it of course,but I have heard all the stories that go along with it.
I HIGHLY recommend the band ‘Its a beautiful day’
Some other classic 60’s bands
Pacific Gas and Electric co.
Here is a pretty good site for more 60’s bands info
