Stein made the transcription for Vienna's Society for Private Musical Performances, a group founded by Arnold Schoenberg in 1918 as a way of presenting large-scale works within a limited budget.
If necessity is the mother of invention, then economy often brings its own aesthetic revelations, and this spacious recording provides a brilliant setting for them.
Steel yourself for a jolt when the opening sleighbells jingle away over piano chords, and don't be too surprised when a solo violin takes up the first theme.
From the start, the sheer adventure of hearing a well-known work anew is infectious. Precision gets priority with Pinnock, who allows his players to milk dynamics for all they are worth. Woodwind are sometimes daringly spirited and two keyboards - piano and harmonium - give climaxes the body they need.
The smaller forces occasionally take you into the later world of Kurt Weill and Fritz Kreisler, linking Mahler to a tradition that was not limited to Symphony Hall.
My only reservation is with Sonia Grane's fresh-voiced but ultimately characterless account of the final song.
Opening the disc, Debussy's Prelude a l'apres-midi d'un faune does not fare as well as Mahler.
Benno Sachs' arrangement is skilful, but the initial flute solo is singularly uninviting and, despite all the piano wizardry, one misses the sweep of harp.
