Now, solve this instance: Review: 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
