This is uncommonly excellent, a cover of a portion of "The Gates of Delirium" from the Relayer album. You really really got to listen to this fellow Tim sing, especially if you know a little about Yes.
I strongly recommend the whole Yes song in context, especially if you appreciate intricate progressive rock - listen here and purchase here. The band is solid on this album, with Steve Howe on guitar and Patrick Moraz on keys.
There is a brief moment toward the end of "Soon" that sounds just like a motif from Wagner's Parsifal - a good side note considering my last post.
There are plenty of great videos of Yes doing this song on YouTube as well. The number of likes on those videos is just overwhelming.

Currently you can also find the entire Yessongs video and even Jon Anderson's Olias of Sunhillow, all great stuff (especially watching a young Steve Howe perform "The Clap" on the former video... check it out.)

Next, Patrick Moraz is an absolute genius. Check this out -
