New discovery (for me): the Sirius [string] Quartet. From their web site:
“Born and bred in the downtown scene of New York City, the Sirius Quartet blends the precision of classical music with the energy of a rock band. The four conservatory-trained musicians are also highly skilled improvisers. Whether playing acoustically or with electronic effects they push beyond the conventional sonic vocabulary associated with string instruments. From Lincoln Center and the Köln Triennale to the Knitting Factory and CBGB’s the Sirius makes itself at home in a wide range of venues and musical styles.
For over a decade the SIRIUS QUARTET has championed innovative music. Expanding beyond the classical repertoire, these four strong improvisers and composers have enjoyed performing works influenced by rock, jazz, and other popular styles. Through this interest in popular music the Sirius has developed a repertoire of electronic music for strings. These pieces are more than simply a louder, amplified quartet; these pieces hope to widen the sonic palate of the string quartet through processing.”
