I have a recording from the sweet spot of a soloist playing Rondo a Cappriccio Opus 129, but the noise floor was too high on the omni's that I used, thankfully I was able to rescue it with Sound Forge... Was hoping that my UA-5 and Superlux's were here, but they didn't arrive so it will be AT853's (flying white mics!) for this... As most of these kids will not be that good I could prolly just use a plaskool recorder but at least it is good practice...
