Starting this weekend, visitors to Fort Mason’s newly renovated former machine shop, Gallery 308, will get to experience 400-year-old choral music while gazing at views of the Golden Gate Bridge. Artist Janet Cardiff’s sound installation, “The Forty Part Motet” features forty speakers playing a 16th century work rumored to have been composed for Queen Elizabeth I. The installation concludes the SFMOMA’s “On the Go” programming, as the newly expanded museum is set to reopen in May.
