What is immediately striking is the astonishing sound quality of this CD: it has more than 40 years, so we did not know that he would one day be published! The remastering work, "cleanup" is exemplary. And then it is no less breathtaking musical quality 75 minutes of the concert. Finally we will praise the diversity of titles offered. People may criticize, quite rightly, that this is often the same securities returning in public albums. I do not make the list here. Luckily here there are much less common songs like "Mystery train" or "Away in India" and "Crossroads Blues" or amazing versions as "The Soft Parade," "Roadhouse Blues" and "Light My Fire" with its 11 minutes and without length because the musicians will include digressions, surprising inserts. "Universal Mind" is superb. Finally there is virtually no spoken intro, or "tuning" longuet. In short, and certainly I do not know them all, but in my opinion, this "Pittsburgh" is really THE posthumous live cd to possess emergency.
