Which band does sound like pink Floyd to you out of the ones mentioned?

Skip Spence always was unlistenable to me - and I really tried.

So I suppose you are calling it Barrett-like on the weak, wide-sweeping similitude that it is just that - unlistenable rubbish like Barrett's "Opal".

Psy-fi's two recommendations are UK popsike of the period of earliest Floyd, so they come closest.

But there are many UK bands of the period like this.

At their earliest Floyd were not that big, so they would not have sparked much emulation. That came with the later bands - Walter Ghoul, Virgineers ... - doing them a tribute.
