Karajan didn't change his viewpoint OR interpretive finesses between his analog or digital recordings of Tchaikovsky 4, 5 and 6th. Nor did he get refined playing from the VPO or BPO to displace better recordings in the catalog. These VPO recordings came after Karajan's ego-massaging TELEMONDIAL project (where some of the WORST Beethoven was set to digital memory) and his decline with the BPO had occurred. DG was so CHEAP in limiting the play time to 48 minutes - where they could have included on a 2 disc set, his VPO 4, 5, 6 OR put incidental pieces on each single symphony recording. But no matter, it's hard to believe these worn out recordings are still in DG's catalog. Two Tchaikovsky 5th's that come to mind that surpass this (it's clear the VPO did hand Karajan "the keys" as they did Bernstein and Giulini) 5th would be Previn/TELARC with the Royal PO in gorgeous, creamy smooth sound. On Chandos, an energetic 5th, vigorously played with the Oslo Philharmonic/Jansons, great performance, great "real" sound, real orchestral achievement, smooth elegant playing. Either choice, among others, is better Tchaikovsky than Karajans.
