String Theory, formerly known as Blue Galaxy String Project, is an instrumental pop group formed in 2005 that plays an eclectic mix of originals and modern pop songs arranged for string quartet plus acoustic bass and drums. The group is comprised of six conservatory trained musicians representing Northwestern University, University of Cincinnati College Conservatory of Music, Indiana University, University of Alabama and Davidson College. The musicians are united by a common passion to expand their musical repertoire beyond the traditional roles of the string quartet. Musicians are Caroline Nordlund and Pei-Ju Wu violins; Melanie Rodgers, viola; Sam Nordlund, cello; Abe Becker, bass; Michael Glaser, drums.
