Normally it takes a rainstorm to move the W.D. Packard Concert Band indoors during the summer.

This Sunday it wasn’t weather, but a world premiere that dictated the move.

The band will premiere “Terra Incognita,” a new composition for accordion and wind band written by composer Stan Bann and featuring Joseph Natoli of Howland on accordion.

“Because of the nature of the piece, I just felt we should play it inside,” said Thomas Groth, executive director of the band. “It’s really hard outside to get a good sound, and this is a major work. We’d like to have people hear it and also get a good recording of it.”

Natoli commissioned “Terra Incognita,” and Sunday’s performance will be the kickoff for the GR8 IDEAS Digital Accordion Symposium, which runs through Wednesday at The Grand Resort in Howland.

Natoli is co-founder and director of GR8 IDEAS, an organization dedicated to expanding the audience for digital accordions. He writes music for both acoustic and digital accordions, and his seven CDs include original compositions covering a wide range of styles, including classical, Latin jazz, orchestral and tango.

Natoli started his accordion studies at age 7 with the late Mickey Bisilia of Youngstown, and he earned his bachelor’s and master’s degrees from the University of Toronto, where he studied with Canadian accordionist Joseph Macerollo.

Bann is a Berklee College of Music graduate whose compositions span a breadth of types and styles of ensembles.

His pieces have been performed by the U.S. Air Force’s Airmen of Note, the Civic Orchestra of Minneapolis, Bones West, the Phoenix Horns, Berklee College of Music’s International Dues Band and various college and concert bands around the country.

“I listened to the synthesized recordings of it, and I’m looking forward to having the band rehearse it and play it,” Groth said. “I’ve never heard of a piece that was written for accordion and concert band or wind band. This will be something unusual.”

Natoli also will be featured on Aaron Copland’s “Fanfare for the Common Man” at the concert, which will be conducted by Galen S. Karriker.

Other selections will include Clifton Williams’ “The Sinfonians,” Lary D. Daehn’s “As Summer Was Just Beginning,” selections from Mancini’s “Mr. Lucky,” Karl L. King’s “The Trombone King,” a “Polka Party” medley arranged by Paul Murtha and John Philip Sousa’s “The Gladiator” and “Stars and Stripes Forever” marches.

This year’s musical excellence recipients will be recognized during the concert. Tileah Johnson-Goodrich, a 2026 Warren G. Harding High School graduate, will receive the George Garstick Award for Musical Excellence. Samuel Chapman, a 2026 Lakeview High School graduate, will receive the Donald W. Byo Award for Musical Excellence. Both plan to attend Youngstown State University’s Dana School of Music.
