There's little point in discussing the music of Relayer and it's importance in prog rock as others have done so at length elsewhere. What's great about this particular release is the beathtaking sound quality and bonus tracks provided by Rhino Records. A vast improvement over the original CD remaster, this is Yes sounding better than ever. Each instrument stands out in the mix, the highs are more crisp and the lows deeper. A great deal of the original tape hiss has also been removed. I heard nuances and layers of sound on this release that I'd never heard before; it was like listening to the album for the first time again.
As for the bonus tracks, the single edits of "Soon" and "Sound Chaser" are somewhat superfluous, but the alternate version of Gates of Delerium is quite interesting. I won't give too much away, but I will say it's fascinating how much it varies from the album version.
With crystal clear sound and almost 30 minutes of bonus material all at a budget price, this re-issue of one of Yes' classic albums is a great value for any fan of progressive rock music.
