I'm with Yorky, the sort of stuff that was called psychodelic/underground/progressive .
I could add Cream, Soft Machine, Captain Beefheart, Pink Floyd and others to the list
And yes, I'm showing my age; as a baby boomer I was a teenager in the 1960s and will be 69 this year. I can remember when the Beatles, Rolling Stones and so on started
I watched a TV documentary about 60s music a couple of years ago where one of the commentators said - " I am forever grateful that I lived through that magical time when Mod changed to Hippy".
I also have my favourite guitarist - Michael Chapman
