What is a good intro to "Mahler"?

From used specialist dealers you can probably find:
Mahler 3 Horenstein Unicorn pressing. Not Nonesuch.
Mahler 2 Klemperer EMI pressing NOT Angel.

I'm looking for the LP Mahler #3 Horenstein....difficult to find (so far)!

Ethannnn, try also to get the Klemperer Mahler 4, available currently from the mail order dealers as one of the EMI reissues (Testament?). And hey, if your speakers don't go too far below 50hz, maybe the Cisco will be listenable?

Thanks for the tip, I am new to classical and vinyl so I expected making some mistakes. Can you recommend a good recording of Beethoven's Egmont Overture? I have a copy from Classic records but felt the pace was too slow. I'm looking for pieces that are grand and engaging, ideally with moments of delicacy. The ONLY 2 classical records I own are Beethoven's Egmont Overture and the pending Mahler 5th Symphony. Any recommendations on recordings currently availble on LP that I should try?

Thanks,

By the way, I do have full range speakers with full tube equipment so I'm curious to hear what the Cisco recording will sound like. :)

ethannnn, I realize that your into LP's big time - i don't know what your CD source stuff is - i assume its up to speed, therefor - Unfortunatly, Mahler didn't get recorded a lot before Walter, Bernstein and Abravennel in the 60's. Good vintage Mahler LP's are very hard to find - There are many excellent CD's of Mahler performances that are arguably much better than what you will find on the lp's that are generally available on the used market. If you're into excellent performances of mahler, ask - if you just want lp's currently available, i can't help.
