I've had the opportunity to play this one twice, with Athelas in Copenhagen and two years later with Studio 6 at the BEMUS Festival in Belgrade (for which we still haven't been paid BTW, after 15 months...) Unfortunately the full-length video footage has mysteriously disappeared, but we were able to get some short snippets that one friend filmed from the audience. So, you can still hear a short fragment from a rather long trumpet solo in the last scene.
CODEX I. From the TV feature on Ensemble Studio 6, aired in April 2013
CODEX XII. The premiere, 28. 4. 2013. KC Rex, Belgrade
Recorded live at the Studio 6 concert in CK13, Novi Sad on June 28, 2014 (I remember watching Brazil beat Chile on penalties seconds before going out on the stage)
This is just an excerpt (last part of the 2nd movement) and the full recording will appear on CK13's live compilation release that is scheduled to come out in early 2015. A studio recording is also planned as a part of the Studio 6's long term project to record all of his solo pieces in a CD box set.
I was always terrible at acquiring, keeping and uploading my own recordings; so here are mostly some audio and video links I could scavenge from various sources around the internet, in no particular order. A lot of the really good stuff is missing, but that's how it is...
