Free tickets are now available January 4 at 10 a.m. for the 2017 season of “Concerts from the Library of Congress, ” which includes not only concerts ranging from classical to jazz and pop, but also lectures, films, book discussions and interviews with composers, performers and scholars. The series is made possible through Library endowments funded by private donors. The events, most held in the Library’s Coolidge Auditorium, are free but you must have tickets (paper or digital) for admission. Tickets are distributed through Eventbrite, with no service charge. For details, a schedule of performances and links to tickets, go to the Library of Congress website. Tickets are not required for pre-concert presentations or weekday daytime programs.
