I currently sing with San Francisco Renaissance Voices directed by Todd Jolly, mostly as an alto, but I also moonlight as a soprano. I first joined SFRV in August of 2007, singing in the chorus of the Baroque opera "Solomon." Following the opera, we performed a Halloween concert featuring English renaissance music. We're in the process of making a CD of this concert. Look here for information when the CD is released.
SFRV are now singing Franco-Flemish renaissance music. The first concert of the season was the Feast for Saint Valentine. Below is a YouTube montage of that concert. I had the honor of playing the 'bailiff' (you can see me at 1:32):
For more information about the rest of SFRV's season, about tickets, or even about the group itself, you can find all you need at SFRV's website: http://www.sfrv.org/
Occasionally I sing with the 9:30am Sunday Mass, directed by Tim Murphy.
I sometimes cantor for the 4:15 Saturday service.
