This is the story of a late 1800 chamber music ensemble named "Dix Moitié". Apparently, this ensemble is the one who make dixieland-like arrangements from classical music from the beginning of 19th century (early 1800).
However, it's not known if this story is real, fiction or a mix of both.

This is an excerpt from the original website www.dixmoitie.com:

The scores:

These are mainly reductions for mixed chamber quintet of famous works from the first half of 1800. The instrumentation, as shown by the scores, is as follows: clarinet, cornet, trombone, tuba and mandolin. Apparently normal reductions of famous music pieces, like La Traviata, La Carmen, some Chopin nocturnes and rearranged piano pieces, at a closer look, have some special features that suggest something original, like the half-value augmentation dot.
But this work contains strange spots, not only from a technical point of view compared to the period it was made. The decision to make an album that sounds as close as possible to the versions found in the manuscripts (listen to a sample), derives from the fact that these arrangements, although dating between 1880 and 1890, at a first reading, sounded much like the music of New Orleans of two decades later. This was the first strangeness. An anachronism to overcome, but how?
