I'm waiting for it still. I The first two discs are the famous TMoQ/Blimp source. The third and fourth disc collects so called third audience source, which was recently issued by the Golden Eggs earlier this year. The fifth and sixth disc reissues newly relased source matrix.
I have:-
The Original Cobla, The Eat a Peach & The Graf Zeppelin
So other than the TMoQ/Blimp source, (Which is NOT the whole recording), which appears on the Graf, the recordings on the New 6CD set are not duplicated on the ones I have plus I have the bonus of the new Matrix on CD in a very nice set!!
