"Subrosa Subway" hooked me right in. "Calling Occupants" a masterpiece. No one thought it could be done...the Beatles sound in an experimental way, but my goodness, an attention and care to arranging was astounding. No mop top hype to hide behind.The fact that they wanted it released with no individual song credits made it feel like a group effort. As they wanted no one to look at the album in none other way than an experience. And they the achieved with flying colours. This album is the reason I even got into songwriting or noticed songwriting as an art form.Indeed a special album for me all time.

This book, published in 1996 and half of which is a directory of shops, was bound to be outdated months after publication much less ten years after, as it is now. Hence the four stars instead of five.Given that, the first part of the book is crammed with a precis or summary of Flusser's recommendations that he has used several hundred pages to expound in his other books ('Clothes And The Man', 'Dressing The Man') and makes the book worth the (used) book price.I do not understand others who warn against this book because they think it is not objective enough! This is a book written by Flusser so of course you will get his subjective view. Had it been written by a committee of tailors, well then, I would expect a more balanced view, but it is not. It is up to the intelligent reader to understand they are getting a product of one man's opinion and then proceed accordingly.

I bought the album as soon as it was released in New Zealand after seeing Nanci on the Bob Dylan anniversary concert video singing "Spanish Boots of Spanish Leather". Apart from this video and the guest appearance with the Chieftans it was hard to obtain videos of Nanci in this country. I have most of her albums. This video is superb. The quality of the concert production is excellent. The background dialog gives you an appreciation of her background. The songs performed are not exactly as per the album which is a bonus as you get to appreciate other ways of producing the songs. The feeling that comes over is the commitment and honesty of Nanci. She communicates with her audience on an awesome level and this is translated into the viewer's experience. This video is a must for all Nanci fans and lovers of mainstream country.David Askew,Auckland, New Zealand
