According to Moonalice legend, there is a correlation between the size of any tribal gathering and quality of the music. In Moonalice-speak, the bigger the pow-wow, the deeper the groove. Someone may even have said, "da bigga da bottom, da betta da buzz," but until October 7, we had no confirmation. Hardly Strictly Bluegrass is a small slice of heaven that appears in San Francisco every October. This year there were 72 bands on six stages over two and half days. And it's all free, thanks to the generosity of Warren Hellman, banjo-picker extraordinaire. The Moonalice band played a 45-minute set at noon on a beautiful Sunday, to an audience that numbered somewhere between 10,000 and 30,000. As pow-wows go, this one was huge, as was the groove.
