The musicians of the Jupiter String Quartet sometimes call themselves “the Jupiters,” and it’s no wonder since it is a family affair. The group is anchored by two sisters, Liz and Meg Freivogel, violist and violinist, respectively. Completing the group is Meg Freivogel’s husband, cellist Daniel McDonough, and violinist Nelson Lee.

The arrangement works. The quartet has been together since 2001, trained by mentors including the Takacs Quartet and the Cleveland Quartet. It is on the faculty of the University of Illinois and also holds visiting residencies at Oberlin Conservatory and Adelphi University. The “Jupiters” have recorded music by Mendelssohn, Beethoven, Shostakovich and Britten for Marquis records. It has also recorded American music by Barber and Gershwin for iTunes in conjunction with the Chamber Music Society of Lincoln Center and Deutsche Grammophon.

Next weekend, the Jupiter Quartet is playing two concerts in the Slee Beethoven Quartet Series in Lippes Hall in Slee Hall on the University at Buffalo North Campus, Amherst. Tradition dictates the order of the music.
