RSQ was formed in the summer of 2012 as a legacy and a living memorial to the late Raphael Spiro (1905-2000) when the three upper string players learned at a chamber music gathering that their principal violin teacher had been Mr. Spiro. RSQ performs formal recital concerts, gives educational workshops for audiences ranging from elementary to college level, contributes to local community and neighborhood outreach programs, and is available for weddings, parties and celebrations for all.   RSQ are recipients of two Oregon Regional Arts and Culture Council (RACC) grants, one to perform for young audiences; and one that was a collaboration with Cascadia Composers and the Children's Cancer Society to perform new compositions for children residing in hospitals.
