[EX Q]: Considering how much bad music is out there these days, this was nice to come across. Covers a wide range of topics and moods, musicianship is pretty good. I'd recommend it to just about anyone. My tastes are usually heavier and more progressive - Rush, Dream Theater, Iron Maiden, Queensryche. But I like this disc too.
[EX A]: Positive

[EX Q]: I wouldn't recommend this book to an enemy. True, the information may be worthy, but the writing style and the narration were horrible. It is definitely NOT written (nor read) in a conversational manner. I'm willing to cut the narrator some slack as he was only reading what was written, however better inflection, phrasing, pauses, etc... would have greatly helped this otherwise tedious book.I couldn't even finish it. I suffered through the first 5 disks and after all that investment in time I couldn't bring myself to listen to the 6th. Its just that poorly written.I'll restate the fact that the message -- the information -- is worth hearing, its simply written in such a tedious manner that I couldn't stand to hear it through the end.I think I'll donate it to my local library.
[EX A]: Negative

[EX Q]: This is one of the best video concerts ever. The sound, visuals and performances are top notch. It is a real joy. I have owned it a week and watched it 3 times already. Every performance is good. There are no dead spots during this concert and you get quite a number of them. A keeper. Memorable.
