Many songs by Earth, Wind & Fire. Some that come to mind are "After the Love is Gone", "Fantasy", "Get Away". They don't make music like that anymore. Where has the "Spirit of Radio" gone. Rush, another group that could take your mind to other places, and envoke thought at the same time. And finally, "Animals" the whole album by Pink Floyd.
After the seventies and the move away from acoustic sounds, we lost some of that spirit; replaced by technology.
MP3 players. It's amazing, but you have no idea what you missed out on with the move to digital compressed media. Eight tracks sounded better than todays MP3 players. But, without acoustic instruments, nuance is lost.
