Poking around for options to acquire downloads of the Bruckner symphonies, including the performances briefly streamed free in April, I came across the following options on HDTracks.com. In no particular order we have, covering at least B4 through B9:
D. Barenboim, B4-B9, Staatskapelle Berlin, 48k/24, 2015, live, probably the streamed performances were these, $52
D. Barenboim, B1-B9, Berlin PO, 44k/16, 1994, $38
O. Klemperer, B4-B9, Philharmonia and New Philharmonia, 44k/16, quite old and "remastered" in early digital era, $29
E. Jochum, B1-B9, Staatskapelle Dresden, 44k/16, mid-late 1970s, $23
Blomstedt, Haitink, Jansson, Maazel (different conductors for different symphonies) B1-B9, Bavarian Radio, 48k/24, $21
Any recommendations would be welcome; Romy, you're at bat!
