Having just wrapped its third season, this bold experiment in musical cross-pollination presented by the Saint Paul Chamber Orchestra and varying partners may be dubbed a runaway success. Whether it’s the haunting pop vocals of Julia Holter paired with the Spektral Quartet at Amsterdam Bar & Hall or local orchestra musicians playing compositions by Bryce Dessner of the rock band the National at the Walker, the series takes classical music down new, very modern paths for players and audiences. thespco.org
