“Philadelphia’s All City Orchestra Summer Academy—ACOSA, now in its second year—is … teaching the technology skills students need to share their music in 2020 and beyond” from July 20 to 31, writes Susan Lewis on Thursday (7/30) at radio station WRTI (Philadelphia). “The Philadelphia Orchestra’s principal timpanist Don Liuzzi, who led Philadelphia’s All City High School Orchestra for 10 years, continues to work with the ensemble. This summer, he’s helping [Philadelphia middle- and high-school students] prepare a virtual performance video conducted by Yannick Nézet-Séguin…. Each afternoon features … a choice of collaborative learning sessions, with student led collaborations, and teacher led technology training…. There are also special courses and workshops with professional musicians…. Beyond the music, ACOSA offers yoga with Project 440, organization founded by Philadelphia Orchestra bassist Joseph Conyers to help students use their music to connect with and improve their communities…. Each student has been equipped at home with a laptop, and ‘Camp in a Bag,’ which includes among other things, T-shirt, notebook for composing, and earbuds with a microphone—important for recording themselves on their cell phones.” The program’s virtual performance will be streamed on August 11 at 11 a.m. ET at the Mann Center’s Facebook page.
