There is a magic percussion instrument on track two, that I though maybe was balanced in her foot, but sadly the other girls walked over it and it made no noise. Their 416 is also quite magic - at the angle to their mouths they sound like a typical cardioid. The lettering facing upwards, however, is an indication that it could be a 418 - which has to have the writing upwards or downwards to operate in stereo. I just find the wispy bright in your face sound difficult to balance with what I know 416s sound like. This doesn't sound like a 416, and a 418 is a 416 with added figure of 8 capsule. All that said - the sound of the speech and chat, and the creaking piano stool suggest more than just one mic - there's one on the piano, but is that for her vocal facing that way or the piano. However it was done, it works really well. The only weirdness is the audience - they're distant, and off mic, but the three girls seem clean all the time?A really mystery.
