Reading Arthur C. Clarke's The Songs of Distant Earth while listening in the background to Mike Oldfield's delicious music inspired by the book, and with the same album title, should be great! I have not read the book yet though.

Clarke's The City and the Stars, Childhood's End, and Rendezvous With Rama, are of course masterpieces of science fiction and futuristic vision, and very pleasurable books. Best science fiction I have ever read.
I am sure Lovecraft would have been impressed by the cosmic outlook in these books. Fritz Leiber expressed a similar thought.

A. E. van Vogt was a "diamond in the rough", I find his prose is not very polished or developed and often near unreadable to me. An uneven writer. But at his most inspired, his futuristic visions are bewitching, hauntingly convincing, ... ecstatic, ... and precursor to Clarke.

And don't miss John W. Campbell's short story "Twilight", in a similar vein.
