For the first time in its eight-year history, ensembleNewSRQ will take to the Sarasota Opera House stage to present its concluding concert of the season. “1976” features 40 musicians, who will perform a double bill of contemporary classics, both composed in 1976. “Frankenstein,” by HK Gruber is a “pan-demonium” that sets Viennese children’s rhymes in a setting with a “chansonnier” (or narrator), who pushes his delivery toward the realm of performance art and an orchestra that plays instruments outside their job descriptions. The world-renowned percussionist Mike Truesdell will serve as the chansonnier. The second piece, Louis Andriessen’s iconic and groundbreaking “De Staat” uses passages from Plato to illustrate the connection between music, politics, and social class. The concert is Monday, April 17, 7:30 p.m., at Sarasota Opera House, 61 North Pineapple Ave., Sarasota. Single tickets are $25.
