Is there anybody, who know more on CD's or live recordings of BRAHMS op.
34b for two pianos? The BIELEFELDER catalogue ignore this op.  completely
and only through www.cdwonder.de I could find out more recordings!

1) Martha Argerich, Alexandre Rabinovitch, 1993, unknown, cod .7181871
2) Silke-Thora Matthies & Christian Kohn, 1996, Naxos, 8613916

If there is any owner of such recordings, I would be glad to know a
personal impression on them?
Here I will suggest also a new release:

Laura & Beatrice Puiu, 1998, Caraba, cod. LB7798,
www.caraba.com/page3.htm

I'm also interested in having details on the pianos used (because of the
incredible differences, clarity of parts)

Thanks,
Patrick
