Friends, I have a request. The first time I heard an alternative completion of the Mozart requiem was in a recording with Neville Marriner, I believe, and the Academy of St Martin In-The-Fields. But their Lachrymosa was so different from the one I was used to that I tuned out completely. From that day I have shied away from these non-Sussmayer versions, but maybe I have been too hasty. The version I presently play most frequently is the one by Gardiner and the Monteverdi Choir, but one day when i was paying attention, I was stunned again by the Lachrymosa: it was different from the Sussmayer version. Can anyone who knows about these things summarize what the different versions now available on record attempt to do; e.g. which parts of the mass are different from the Sussmayer traditional version, and how different are they, which parts have been completely re-composed in contrast to being re-orchestrated. Is it the case that Robert Levine's version is a more careful, idiomatic (?) orchestration of the Requiem, leaving the composition recognizably the same as the Sussmeyer version in other respects? So far I have heard about completions by Sussmeyer, Eubler, Maunder, Levine, and Bloch(?) Are there others? Can some kind sould post a summary along the lines I've suggested? arch
