Recently Naxos has issued a 15-CD budget Mahler set featuring the recordings of Antoni Wit and Michael Halasz. I think their 7th (Halasz) is pretty good and Wit's Warsaw PO Mahler 8 is of course highly praised. Halasz's Das Lied also received critical attention in some quarters. Otherwise, I haven't heard much of the rest of the cycle (the bits I've heard (from 1, 2, 3, 6) are rather mediocre), so I wonder if anyone here has heard the rest and if so is it any good?
