I have had on my mind some musical artists who are likely GT.
The two artists I have been thinking about are Siouxie Sioux who people may remember as being part of Siouxsie and the Banshees and the Creatures. The other artist that I have been thinking about is an Australian band called The Church http://thechurchband.com, http://en.wikipedia.org/wiki/The_Church_(band).
My partner is a big fan of Siouxsie. Siouxsie has been performing for over 30 years, and has now moved into a solo career. Siouxsie had never gone farther than High School, though listening to her, the language in her songs, the words and language she uses in interviews, she is far more intelligent the knowledgeble than someone who never went farther than High School. http://en.wikipedia.org/wiki/Siouxsie
The church is a band that I have been following for a long time. They have been around for about 30 years. I have particularly focused on the lead vocalist and writer of many of their songs Steve Kilbey. In addition to writing most of the lyrics, he also plays on the songs in addition to being the lead vocalist. The lyrics are very ecclectic, intelligent, complex, and divergent. Themes in his songs from his interests include the dark side of people, complex relationships, mysticism, legends, myths, poetry, literature. He is also an accomplished artist and his work has been on many of their albums. He is also a complex person, who has had a dark side, including serious drug addiction. Recently I had heard of a concert in New York and decided to go. The audience, a bit more geeky older and intelligent, I felt very much at home and felt that I was among other GT folk, though it also seemed a bit autistic in some ways. It turns out money from sales of merchandise is being sent to a Autism charity. Aparently recently introduced as a Biography about Him and the band called No Certainty Attached. It is very honest and not appologetic about any of the dark side. In reading the biography reading about his upbringing and his education and development, there are many clues pointing to a GT person. The other members of the band who have been together. except for the drummer, the entire 30 years, the drummer came in the picture later. They are also very talented and one wonders about the other members, who may be GT as well, though one would want to know more about them.
