I have the Ruud recording on Simax of the 1893 Hamburg version (It also contains a recording of the Piano Quartet). That's pretty good, but a little hard to find, but available from amazon.co.uk vendors for about GBP 10 (+ P&P).

Amazon.com review (but the recording is out of print):
5.0 out of 5 stars Original Version of Mahler Symphony Gloriously Performed!!, November 5, 2000
By Darin Tysdal (Bloomington, MN 55420) - See all my reviews
(VINE VOICE) This review is from: Titan: Symphonic Poem In Symphonic Form / Piano Quartet in a Minor (Audio CD)
This piece is actually called Titan: Symphonic Poem In Symphonic Form. This does include Blumine and the rest of the work is in the earliest surviving orchestration. Wyn Morris made the first recording of this version, and as that is out of print, this one admirably fills the bill. This is then the real thing, not like those recordings that just throw in Blumine into the text of the revised version. There are many little differences between the two versions and comparing them is fascinating. The big difference is the textures which are sparser and not as big. Clarity is the watchword here, and Ruud delivers. The big moments come out with a will, and are very well done. Very recommendable, along with the only existing movement from Mahler's early Piano Quintet. Great annotations and wonderful sound. The playing is wonderful. Recommended with enthusiasm!
