Yes, I think it's good enough. You have some variety, in that the South America album adds Attila Zoller (and there's a duo of him and Doldinger, also one of Doldinger/Peter Trunk on the live album).... Trunk is an assett, and him and Cees See form a great rhythm section on the live album. The last album has Volker Kriegel on most cuts, and Sadi, too.
Disc 4 is a bonus disc, three quartet cuts, two duos with Hoffmann, the rest is wiht other musicians, incl. Rolf Kühn, Kenny Clark/Benoit Quersion (one cut, with Hoffmann), and some more, including two cuts from George Gruntz's "Jazz Goes Baroque" LP and one cut with Mangelsdorff added to the quartet... all live stuff, pretty nice!
