Close to the Edge, a musical masterpiece, and uses beautiful progression & changes not typical in pop or rock yet show the nature if hours spent playing as a unit with producers like Eddie Offord. Future live versions such as Symphonic tour really give it modern advantages. I've met most every Yes iteration up to 2009 & it is my favorite all time bsnd. And You & I on side 2 is simply a single that could only have been released in this era. With Yes & like prog rock getting to know the songs allows them to grow on you in ways 2:30 minute song differ. Check out Going for the One's "Awaken" done in 2003 at Tsongas or Montreaux Jazz fest 03.
