If you’re someone who believes the drummer is more than someone at the back of the stage who keeps time, this week’s Percussive Arts Society International Convention, otherwise known as PASIC, is your kind of event. Joshua Simonds, executive director of the Indianapolis-based Percussive Arts Society, says the artistry of drummers is celebrated at the four-day event. While Indianapolis is locked in to host PASIC through 2028, this year’s gathering carries landmark significance because it’s the 50th annual edition. Nearly 7,000 attendees, on target to set a new record, are expected to check out concerts, workshops and an exhibition hall. Drummers who play in the touring bands of Taylor Swift and Beyoncé will attend, but PASIC isn’t confined to mainstream sounds. The lineup spans world music, jazz, marching percussion and contemporary classical. In this week’s episode, IBJ arts reporter Dave Lindquist talks with Joshua Simonds about the event, scheduled Wednesday through Saturday.
