In celebration of the Belfast Free Library’s 125th anniversary, a series of special events sponsored by the library’s trustees, Friends group and staff has been arranged for this year. The first of these events, a free concert by the Kräftig Quartet, will take place Sunday, March 4 at 3 p.m. in the Gammans Room of the library, 106 High St.

The Kräftig Quartet formed in the autumn of 2009 under the direction of the late Kathie Johnson of Cushing. The quartet features Fiona Boyd, violin; Duncan Hall, cello; Sam McKenna, piano and oboe; and Teal Vickery, viola. Among the works they will perform at this concert will be the Mozart Piano Quartet No. 1 in G Minor for piano and strings.

Kräftig — originally the piano trio of Vickery, McKenna and Boyd — won the Young Stars of Maine Kathie and Marc Johnson Chamber Music Award in the spring of 2009. After recruiting Hall to form the quartet, Vickery began her study of viola. This revised ensemble was awarded the Kathie Johnson Chamber Music Prize in the 2011 Young Stars of Maine competition.

The group is currently coached by Kirsten Monke of the DaPonte String Quartet and rehearses weekly at the Bay Chamber Music School in Rockport. The quartet routinely performs at the Rockport Opera House and other local venues, and each musician has attended Kneisel Hall in Blue Hill.

The young musicians members attend two local high schools. McKenna and Hall are students at Camden Hills Regional High School, where Hall is involved in drama and chorus and McKenna plays piano in the Jazz Band and oboe in the school’s Concert Band. Vickery and Boyd both attend the Watershed School in Rockland, where Boyd leads the Amnesty International chapter and Vickery balances her academics with ultimate Frisbee and downhill skiing.

Following the performance, there will be a reception with light refreshments. For more information, call the library at 338-3884, ext. 10. For a full list of the library’s 125th anniversary events, visit belfastlibrary.org.
