Ring tones on stage Saturday

Get ready to raise your Razr and brandish your Blackberry.

The first performance of the Missouri Theatre’s Classical Series, a part of the 2007 Hot Summer Nights Season, will marry cell phones and a symphony. The Missouri Symphony Orchestra will perform “Concertino for Cell Phones and Orchestra” as a part of its “Cell Phones and Beethoven” concert.

“We’re on the cutting edge here,” said Kanani May, a spokeswoman for the theater. “It’s the one and only time you’ll hear, ‘Ladies and gentlemen, turn on your cell phones.’”

Members of the audience will be asked to participate in the concert. Conductor Kirk Trevor will cue audience members when it’s their turn to make some music — with their cell phones. Aaron Vandermeer, a cell phone soloist, will also participate in the performance.

The concert will also feature the world premiere of “Ich Schreite Kaum,” by Ralf Gawlick, and finish with a performance of Beethoven’s Fifth Symphony.

Tickets, from $10 to $15, are available at the theater’s box office, or online at motheatre.org.

And don’t forget to bring your cell phone.
