Gaveston, there's a play called "L'Hotel," in which the spirits of deceased artists share a hotel together. One of them is Jim Morrison of The Doors, who finally caves and admits that the reason for his angst is that, as a spirit, he can finally confront the truth about his life. "I was a hack," he says and I paraphrase. "All I was was sex and pretension. I was a bad poet, a bad singer, a bad songwriter and I made the world worse. My image was all I had, not my songs."
Given that I think the Doors at their best DID create interesting and valid music, and that Morrison's overcooked psychedelic poetry may not have been profound but was certainly evocative and appropriate to the music and its time, I disagreed with the play's assessment of Morrison and his legacy. But I think a similar assessment could be made of Janis Joplin: her image and her legacy are of much more profound importance than any of the actual music she recorded.
