Every year (pandemic excepted), San Francisco’s Golden Gate Park is host to the Hardly Strictly Bluegrass festival, a three-day free (!) extravaganza of American roots and roots-derived music. I live close to the park, and marvel that many years — including this one — I get to walk on over and see Nick Lowe play outdoors. Today, the first day of the festival, I caught two acts: Margaret Glaspy and, shown above, the great Marc Ribot. The week’s fog and rain had disappeared overnight, and these sets made for a fantastic start to the weekend. Glaspy (in a trio) and Ribot (solo) were just two of numerous acts on two of the festival’s six stages, the others much larger than this one.
