Next show in Vienna was OTHELLO with director Peter Sellars. I was A2 and mixed mics during rehearsals while sound designer Mark Grey created the sound and music. During the run I maintained the wireless mics. This was busier than anticipated because the AKG 4000 mics sounded great, they mysteriously kept changing frequencies. AKG Vienna was very helpful and are still in investigating what happened. This was a high profile gig with a well respected director, a bright sound designer, and a famous movie actor.
