This appears to be a partial iCalendar (ICS) feed entry for a jazz concert event, published by the website jazz-concerts.com. However, the data is incomplete—it cuts off mid-line without a description, title, date, or location—so I can't tell what the specific event is actually about beyond it being a jazz concert listing.
