The Portland String Quartet will perform at 8 p.m. on Saturday, Feb. 6, at Colby College in Waterville. The performance in Lorimer Chapel is part of the Music at Colby Concert Series and admission is free.

The program will feature compositions by Franz Joseph Haydn, Sergei Prokofiev and Maine composer Tom Myron. Myron, a Portland resident and director of education for the Portland Symphony Orchestra, will lecture about his composition beginning at 7:15 p.m. in the chapel.

Haydn's String Quartet in G Major, Op. 77, No. 1 will start off the evening followed by Myron's Kathe Kollwitz for Soprano and String Quartet. Myron's piece is based on poems by Muriel Rukeyser and will feature soprano vocalist Christina Astrachan. Following intermission the quartet will perform Prokofiev's String Quartet No. 1 in B Minor, Op. 50.

The Portland String Quartet is composed of violinists Stephen Kecskemethy and Ronald Lantz, cellist Paul Ross, and Julia Adams on viola. The ensemble, which has played together longer than any U.S. quartet except the Guarneri String Quartet, has established a reputation for strong performances on its international tours, and its recordings on the Arabesque and Northeastern labels have won numerous honors. The musicians are artists-in-residence at Colby and have conducted a string quartet institute there for the last 23 summers.
