That list is a start, but it's over ten years old now and leaves out a lot of world-class groups. We're actually right in the middle of a golden age of early music performance. I sing professionally with several period instrument groups: American Bach Soloists, Philharmonia Baroque Orchestra, Bach Collegium San Diego, and others.

The first two groups I just listed are in the Bay Area, btw, so concerts are readily accessible to readers in Silicon Valley.
