In the mid-70's, when Haitink and the Concertgebouw were at the height of their popularity, they recorded all the Mahler Symphonies for Philips. The labels sonics weren't the best and Haitink had his detractors but the performances were inspiring: first-rate string ensemble playing, the brass section that the Concertgebouw venue flattered, and excellent choral and vocal work. I found the second and eigth at Amazon as Philips cd re-issues, no mention of the fifth.
