I found this great description of The Doors from a review of The Doors - Live in Detroit. http://www.doors.com/magazine/detroit.html
The veil of time is thin indeed, for despite 30 years since Jim Morrison's departure to the other side, his words, and the music upon which they flow remain as fresh and powerful as during Morrison's lifetime. Like the blind who were returned their sight by a prophet of an earlier age, The Doors awakened the third eye of enlightenment to scores of people--an eye that remains closed for those who shun the quest for inner freedom. To be an artist and a spiritual messenger whose words transcend the barriers of time serves as proof of the attainability of spiritual immortality. It is a curious irony that a great number of the most ardent Doors fans were born years after The Doors disbanded, yet they feel, and are moved by, the words and music with the same intensity as if they had been performed yesterday. As a musical force, The Doors featured an unearthly power that continues to grow and evolve. They planted a seed within the hearts of countless people. The seed has germinated and grown, and whether we partake of the fruit of knowledge or let our minds atrophy in a cloud of conformity is our own choice--the music of The Doors offers clarity so such choices can be made.
