My AM gig featured Indra Thomas, an operatic soprano. She did a few with her accompanist and a few with the band/choir. Big voice, but I couldn't understand a single word she sang. It was all vowels and vibrato.
My PM gig was pretty good. We've finally located a guitarist; he played on two songs with us. Other than that, I spent most of the gig trying soprano reeds and watching the Giants/Cowboys game on my phone. The five hour House Live gig the night before did wonders for my flute face.
