Sunquaker (Jenn Bosworth) was exceptional! She is really talented (during the party, several people stopped in mid-conversation to marvel at how good she was). Jenn and I performed a duet that we had rehearsed several weeks earlier - it was the hit of the party. She was very accommodating, providing me vocal tracks to practice w/ on my own. I won't be surprised at all if several of our guests hire her for events soon. The lower prefessionalism mark (3 out of 5) was because her parents and sister came along to watch her. Our party was a small, intimate affair, so this was rather awkward. But, I would definitely recommend Jenn to anyone. She is truly gifted.
