It's actually a really good intro for people who are not familiar with classical music, or Mahler himself. Carr's book is not written for people who read this forum, it's written for normal people. My Mothers husband only reads biographies, I lent him my copy of the Carr book and he thoroughly enjoyed it. He is someone who doesn't understand anything about music, nor listen to it. That's who this book is aimed at, or someone wanting to dip their toes into Mahler.
