Is Joni "in her own world"?

[Relayer211]

      A few years ago I went to see Joni sing in CT with my mom.My mom's a fan of 
hers(That's how I was exposed to her wonderful music.I grew up hearing "miles of 
isles".)At the concert,my mom didn't like Joni's voice and found her to be out of 
touch and in her "own world".something,I myself,can relate too.Do others see Joni the 
same way?
