Not to argue with you. I'm just quoting what I've read.
I agree. I used to play in altered states in high school in a steady gigging band in the 70s.
I quit playing high in the mid 80s when I started playing in original bands. No big.
According to McCartney they dropped the Maharishi because he was hitting on Mia Farrow's sister, Prudence. Lennon wrote "Sexy Sadie" on the White Album about this incident. John didn't think it was appropriate for a Transcended One to be messin' with the customers. I don't know - wasn't there. But it is on the Anthology DVD in an interview with George and Paul. And no, I don't think they stopped their pot smoking -- except George.Actually, I'm working in Fairfield, Iowa, the seat of the TM movement in the US... The Beatles and Maharishi had their falling out because of their drug use. This would tell me that they weren't over it.
I'm just quoting Roger Waters. "Saucerful" is a really a good book. Can buy it cheap used out of Amazon.Also, I never meant to say that they or Pink Floyd were habitual and constant users of LSD, but that a lot of their very best music was inspired by trips they had taken. It certainly doesn't help you play any better, but it does put ideas in your head that are weird and twisted and can be executed later.

I sincerely believe that the exploratory side of music is much more accessible when sufficiently "chilled out." Technical passages may become less accurate, but it's all about priorities.
