Last night I was able to attend the second of two concerts by the Pacifica Quartet at Portland State University’s Lincoln Hall. It was a wonderful program (if a bit conservative) that showed what a wonderful young quartet the Pacifica has become. The program began with Mozart’s “Dissonant” Quartet, Kv. 465, from his set of six dedicated to Joseph Haydn. The Pacifica’s excellent ensemble, pure intonation and wide-ranging dynamics were given full show here, and their absolutely hushed, controlled, and beautifully blended pianissimos were what truly set them apart from many other accomplished ensembles. Whereas other quartets might bowl one over with their prodigious sound production, the Pacifica’s four members are each able to get down to the softest of sounds while still projecting to the back of the hall and keeping intonation and balance right on the knife’s edge of perfection.
