I too sing in a choir (a good church choir), and I agree with Sugarbrie as to the Scheier performance. Sound is pretty good, and the soloists are top notch. The Boston one that he refers to in his latest is, I think, the Pearlman/Boston Baroque (sp, I'm sure) on Telarc, which I have not heard. It undoubtedly will have good sound, judging by their other discs, which I have, but I've not heard the version they sing. If I'm right on the ensemble, the choir will be smaller than you might otherwise be used to as well (I have their Bach Mass in B Minor).
