Do you build houses (or palaces, more likely?) as they had back then, wearing period cloths (no wristwatches, please), smelling as people must have, and only listen to HIP music after having HIP foods and drinks, too?
EDIT: forgot the most important part: where do you go and inhale the quiet, the silence that must have been around in the world back then?
To me, this is all just one of many ways and I'm somewhat pissed by the ideological twist you so often hear when HIP music is being explained.
