Flute Music for Texas Region Audition...?

Does any one know where I could find a recording of Joachim Andersens C# Minor, Sigfrid Karg-Elert's A-flat Major, or Theobold Boehms Gminor for flute? I am practicing my music for region and it would be nice to have a recording to listen to just to make sure i have all my rhythms right....
Update: The only other thing on the music are these numbers im not really sure what they mean but im sure one of u smart people does, Andersen is Op. 21/10, Karg-Elert is Op. 107/17, and Boehm is Op. 26/6
