Folklife News & Events: Klezmer Jam with Howard Ungar and Seth Kibel September 12, 7 pm

Please Join us for an American Folklife Center Summer Music Jam: Klezmer led by Howard Ungar and Seth Kibel

September 12, 2019, 7:00 to 9:00 pm 
Veterans History Project Information & Welcome Center (LJ-G51) 
Thomas Jefferson Building, Library of Congress

The American Folklife Center's series of informal jams to celebrate our living folk traditions, and to bring to life the collections from our vast ethnographic archive continues in 2019. This jam will be led by Howard Ungar and Seth Kibel. So grab your violin, clarinet, trumpet, or other instruments, and come on over to the Library of Congress for the Klezmer Jam.

Seth Kibel is the leader, clarinetist, and composer for The Alexandria Kleztet, an innovative award-winning klezmer band he founded in the Baltimore/Washington area. The band has released four albums that all recieved the Washington Area Music Award for best album upon their release. In addition to his activities with The Kleztet, Seth has fronted a variety of swing and jazz groups, including Bay Jazz Project.

Klezmer trumpeter Howard Ungar founded the DC Klezmer Workshop. Howard has been playing klezmer trumpet since he attended his first KlezKamp in 1999 and has attended many KlezKamp, Yiddish New York, and KlezKanada festivals. He is a founding member of the DC based klezmer band Mrs. Toretsky’s Nightmare, who have played at numerous weddings, bar-mitvahs, and holiday events. You can also hear him playing trumpet with the DC based Machaya Klezmer Band at the Washington Folk Festival and other venues around town. 

This event is co-sponsored by the DC Klezmer Workshop
