The Catalyst Quartet performed Thursday (6-12-14) at Harrigan Centennial Hall, as part of the Sitka Summer Music Festival’s free “Bach’s Lunch” concert series. The group has collaborated to arrange Bach’s Goldberg Variations for string quartet. In the process, said festival artistic director Zuill Bailey, they’ve transformed the classic into “truly new music.”

The Sitka Summer Music Festival continues through June. You can find a full schedule of events at sitkamusicfestival.org.
