... one was "Tommy" by the Who.
After listening to it many years ago, it hit me that this was a song about all of us, how we're blinded and tormented by other people, how we are held back and trapped by materialism and cruelty. Deafness and blindness are metaphors for what we all go through, and how we are held back spiritually during our time on earth.
A similar epiphany while listening to "Days of Future Passed"....an entire lifetime portrayed by a single day, such brilliance.
These albums and others are like great literature, only set to music....some soar pretty high.
