Dry Ice & Gourd Stabbin', and Everyone's Favorite Instrument

Every so often we get a glimpse into the creative processes of League of Legends and the champions. We have seen how the artists work, the pros and influencers testing champions, the balance team making questionable decisions from time to time, etc, etc. What we really have yet to see is the Audio Engineers in action. The most we have seen is in the video about Thresh's Dark Star theme (they have this awesome idea to use dry ice), a guy stabbing a gourd in Irelia's rework video and a Sai being used as a chime (I'd like two please.)

I personally am fascinated with the creativity behind the audio in League of Legends. The voice acting, music scores, and yes the slicing of gourds, but I'd personally want to hear more about the Audio Engineers. Does anyone know any Riot Audio Engineers? Or is that done by a different group?
