Okay had a listen to this set. Discs 1 & 3 are watered down versions of swing played by musicians trying to sound like American bands and not succeeding very well. Disc Two is comprised of vocals first sung with legit lyrics and then morphed into propaganda slamming Churchill. FDR. Blacks, Jews and other enemies of the nazi regime. Its interesting to listen to for about 3/4 of the disc. Disc 4 is notable for the tracks with Django and the rest is mediocre.
The booklet is 60 pages long and is very comprehensive and has almost more information that one cares to know. Goes into detail about the musicians who worked with the nazis to grind out this music, most of whom either perished during the war or were blacklisted after the war for their roles in the propanda effort.
Its a set that is probably good for one listen and then gets shelved for awhile. For 17 bucks, its not a bad deal though.
