O'Neill cylinder (en.wikipedia.org)

An O'Neill cylinder would consist of two counter-rotating cylinders. The cylinders would rotate in opposite directions to cancel any gyroscopic effects that would otherwise make it difficult to keep them aimed toward the Sun. Each would be 6.4 kilometers (4 mi) or 8.0 kilometers (5 mi) in diameter and 32 kilometers (20 mi) long, connected at each end by a rod via a bearing system. Their rotation would provide artificial gravity.

I'm not as much of a fan of these remixes as the originals, but still good.
I listen to SJ5 as good atmospheric driving music for misty grey days or drives up through the mountains.

Yes because much of these original art are in the public domain, they've spread everywhere! Really helped the idea to stick https://publicdomainreview.org/collection/space-colony-art-from-the-1970s/
