The Center for the Performing Arts at Penn State will welcome the virtual return of the groundbreaking Kronos Quartet in a presentation of the string ensemble’s performance film “Testimony.” The free concert recording features music and spoken-word artists reflecting on current events in the United States. “Testimony” will be available to watch from 7:30 p.m. Wednesday, April 14, until 7:30 p.m. Wednesday, April 21 at cpa.psu.edu/events/kronos-2021. The program is part of the Center for the Performing Arts 2020–2021 “Up Close and Virtual” season. “Testimony” was recorded in October in an empty Bing Concert Hall at Stanford University. The musical reflection of modern history features a nod to Jimi Hendrix’s version of “The Star-Spangled Banner,” as well as new works by Rhiannon Giddens, Charlton Singleton, Meklit and others. Kronos also performs to audio clips by up-and-coming California spoken-word artists, including Jarvis Subia, Zouhair Mussa and Anouk Yeh.
