Concert· Düsseldorf
Sarah Christian, Tanja Tetzlaff und Freunde 3
This appears to be a chamber music concert featuring violinist Sarah Christian and cellist Tanja Tetzlaff performing together with guest musicians ("und Freunde" = "and friends"), likely as the third installment of a concert series. As I don't have specific details about this event, I'd recommend checking the venue's or the artists' official websites for the exact program, date, and location.
