Having recently been smitten by Juanjo Mena’s Chandos recording of the Sixth, http://www.colinscolumn.com/juanjo-mena-and-the-bbc-philharmonic-record-bruckners-sixth-symphony-for-chandos/, and further enlightened by a (sadly incomplete) Furtwängler version, http://www.colinscolumn.com/wilhelm-furtwangler-conducts-bruckner-6/, here is Celibidache’s considerate conducting of it, which may or may not be the performance available on EMI/Warner (I haven’t checked).

Bonus video: David Hurwitz on Bruckner 6.
