I had to be allowed the good fortune to sing in the children's choir in 1998 and have therefore quite a lot of shows and various performers live and even a small piece of privately witnessed what me, so I think a pretty big judgment allowed.
The songs of Joseph are just diverse and should be in every collection. However, I agree with the criticism that the occupation of the CD leaves something to be desired. It would have been really great, would Koffi Missah who sings on the Starlight CD Electra, or Uli Scherbel made to Joseph, because the two are vocally simply miles better.
But Andreas Biber was nunmal the mascot of Joseph and played at the time of recording the Erstbasetzung.
Nevertheless, the CD should be in every shelf: even if there is no longer Joseph in Germany, he lives so on.
