Chicago violist Doyle Armbrust graduated with honors from Northwestern University and went on to study with Donald McInnes at the University of Southern California where he earned a Masters Degree in Viola Performance. Doyle is a founding member of the Spektral Quartet and principal violist of the Firebird Chamber Orchestra in Miami, FL.
After returning to Chicago having completed a three-year fellowship in the New World Symphony as rotating principal violist under Michael Tilson Thomas, Doyle began an active freelance career including commercial engagements as sideman for Eddie Vedder, The Beach Boys, Richard Marx, Lupe Fiasco, and Peter Gabriel. Positions not involving pyrotechnics include sectional coach of the DePaul and Roosevelt University orchestras, as well as adjunct viola instructor at the University of Chicago, where the Spektral Quartet is ensemble-in-residence.
A rabid advocate for new music, Doyle is a core member of Ensemble Dal Niente as well as a contributing writer for Time Out Chicago, Beats Music, and the Chicago Tribune.
