With the warm weather in full swing, and now that the organizers behind the Stern Grove Festival have unveiled the complete lineup for the 80th annual festival season, it feels like summer. For real. Now embarking on eighty years, which is undoubtedly a very long time for any series, the festival continues with world-class performances set in the woodsy Sigmund Stern Grove and is still admission-free after all these years.
