C’est une initiative vachement (meuh) intéressante du site FMA que je vous partage ici.
En effet, il s’agit de  remixer divers titres du domaine public, disponibles sur le site archive.org. Alors si vous souhaitez participer, n’hésitez surtout pas ! Surtout que vous pouvez gagner un Moog Etherwave Theremin.

Tous les détails en anglais :

Ever thought Wagner’s “Ride of the Valkyries” would be better as a speed-metal guitar solo? Or perhaps Tchaikovsky’s “1812 Overture” would sound great performed by a kazoo-and-firecracker ensemble? What about “In The Hall of the Mountain King” as a chiptune odyssey?

Great ideas, right?! We know.

We want these things to exist. And we need your help in this Masters Remastered Challenge!

First, choose a composition from the public domain. If you’re stumped (or can’t remember the original name of the composition), check the list below for some ideas. Though you can find sheet music in a variety of places, we recommend the Petrucci Music Library, which indicates public domain status of its contents. Entries will be released back into the public domain with a CC0 license, so that others can use them, too. But make these your own. Remix them, play them with instruments the composers couldn’t have dreamed of, make them as long or short as you want. Do as many (or as few) as you please.

Here are some recommended pieces you can extract from, re-work, play backwards, etc, that are in the US public domain. We’ve included links to the sheet music and at least one downloadable file that you can riff on:

Bach – Toccata & Fugue – listen here – archive.org – wikimedia
Beethoven – Symphony no. 9: Ode to Joy – listen here – wikimedia – freesound
Bizet – Toreador Song – listen here – wikimedia – archive.org
Grieg – In The Hall of the Mountain King – listen here – freepd – wikimedia
Offenbach – Orpheus in the Underworld – listen here – wikimedia
Ponichelli – Dance of the Hours – listen here – wikimedia (BY-SA)
Rossini – William Tell Overture – listen here – wikimedia
Tchaikovsky – 1812 Overture – listen here – wikimedia
Wagner – Ride of the Valkyries – listen here – archive.org

If you submit a song that isn’t on the list, please make sure it is in the public domain before you proceed. Submissions that are not in the public domain in the U.S. won’t qualify for judging.

We’ll accept entries from March 9 until April 3, 2015.

One winner will be chosen by our panel of judges, and they will win a Moog Etherwave Theremin.
