Seeking recommendation for Mahler 2

I don't think you can go wrong with any of the following: Solti/London Symphony (as mentioned by Abysmillard), Klemperer's EMI Philharmonia Orchestra performance, Bernstein's New York Philharmonic reading on Columbia, Bruno Walter's with the same orchestra on the same label as Bernstein or Kubelik's Bavarian Radio account on DG.

Slight correction: Though both the Bernstein and Walter performances were issued originally on the Columbia label (I own the lps), Sony later took control, so you will find both currently on that label.

I recently heard this one at carnegie hall conducted by
Pierre Boulez and was comletely blown away! Such a great work

For multichannel SACD, the best choices today are the MTT/SFSO and the Fischer/Channel Classics. They are remarkably "right" all the way through although the pacing of Fischer's last movement seems to lose a bit of elasticity. Sound is excellent on both with the edge to Fischer.

I understand that the Bernstein/Columbia from 1963 has been issued by Sony/Japan in MCH SACD. I have not heard it but the original performance is explosive. (Gotta get this one.) His final NYPO on DGG is a polar opposite, building tension slowly to a nearly overwhelming finale. (I was privileged to be at his last M2 with the NYPO.)

Solti doesn't do much wrong but he doesn't do much for me. There are many, many other options of note including Klemperer, Walter and, believe it or not, Rattle/EMI.

How can you have only one (or two)?

you can't go wrong with simon rattle's 1984 version with the cbso.excellent recording also.
