Celibidache once described that ''Bruckner's Eight Symphony is the zenith of symphonic writing''... And Giulini once realized one of the greatest Eights ever recorded and performed (with Wiener Philharmoniker, in 1984, on Deutsche Grammophon-Masters, Studio recording, DDD - See my Bruckner list)... This live recording(ADD-stereo) was made with Philharmonia in Royal Festival Hall in 1983; now on BBC-Legends. As recorded sound, ofcourse this is not in 'high' quality when I compare with his studio recording. However this performance is also great and good recorded. If you have Giulini's studio version (now,out-of-print) and if you loved it, you'll love this too. If you have not,you must buy this one: Same class orchestra, same class interpretation and same Giulini !... Magnificient, intense, emotional, rightly structured, honestly conducted and relatively slow...You will need to cry...Highly recommended...Trust me...
My favorite & 'great' Eights : Knappertsbusch (1963-MP, on DG-Westminster), Giulini (1984-WP on DG; 1983-PO live,on BBC), and Karajan (1957-BP, on EMI and 1975-BP & 1988-WP, on DG).
In my opinion, other very good & important recordings: Jochum (1976-SD, on EMI), Bohm (1976-WP,on DG), Wand (1979-Köln, on BMG/RCA), Celibidache (1993-MP live,on EMI), and Maazel (1990-BP,on EMI).
