I do have to warn you about Relayer, it's one of my favorites now but it took me a couple of listens. Gates of Delirium and Soundchaser are considered the most inaccessible pieces of music they've ever done. Gates especially, it's a 20 minute long song about an epic battle and it's a very challenging listen, you'll either love it or hate it.
I certainly don't think you'll consider this one boring though.
Oh, and one more thing, theres a certain part during Soundchaser where Jon Anderson sings "cha cha cha, cha cha" repetitively. Just so you know.
