Personally, I believe Chuck's solo on A Moment of Clarity is perfect. Technical and melodic goodness, its a short solo, but one of my favorite guitar solos ever made. Really love that solo and all of TSOP
Honestly, this might get me removed from this subreddit but, I believe Nevermind is the WORST out of the big grunge albums (Dirt, Superunkown, Core/Purple). If you remove the impact factor of it, i think you get a fairly above average grunge album, with a few really good songs. I think its overrated too, yes, again, its impact is undeniable, but I dont think its THAT good of a project as compared to something like Dirt or Superunkown.
