Ready for Tuesday night tunes, symphony style? We visited the Chief Sealth International High School Auditorium tonight as Rob Duisberg was leading the Westside Symphony through rehearsal for tomorrow night’s concert (second half of a two-Tuesday doubleheader for the groups now collectively known as the West Seattle Community Orchestras). Bach and Beethoven both are on the program – as detailed here; $5 adults, $1 kids are the suggested donation amounts (more gratefully accepted, of course), with concert time 7 pm Tuesday (2600 SW Thistle).
