Early Pink Floyd albums

I do love the early Pink Floyd. I was going to give you the Ummagumma version of Careful With That Axe Eugene with Roger Water's bloodcurdling screams. But then I moved onto Astronomy Domine and found a recent version by David Gilmour. I've heard him say that his guitar style and Syd Barrett's are 'not even close' but here he is doing Barrett's song, Barrett style. Lovely. https://www.youtube.com/watch?v=rLBxJL5G3EE
