<p>My daughter is in the Carleton choir, and just joined an a capella group. The a capella groups are very popular, and there are several of them. They will have auditions shortly after the fall term begins. The choir gives 3 or 4 concerts a year, plus a trip (they just got back from performing in New Orleans). The repertoire is quite diverse - very few “dead white males”.</p>
<p>Not sure about instrumentals, though.</p>
