The Laguna Concert Band will put on a "Musical Spooktacular" at 3 p.m. Sunday at the Laguna Playhouse.
The show will feature guest artist Gary Gould, who will play a rarely heard instrument, the theremin. It makes an eerie sound and is played without any physical contact.
Gould will perform "Transylvanian Lullaby," which is based on the theme from "Young Frankenstein."
Music from the "Harry Potter" and "Pirates of the Caribbean" films will also be performed, according to a flier for the event.
Tickets are $10 and may be purchased at the box office or by calling (949) 497-2787. The Laguna Playhouse is at 606 Laguna Canyon Road.
The Laguna Playhouse will hold its third annual Moonlight Masquerade at 6:30 p.m. Saturday at Tivoli Too.
The Halloween party doubles as a fundraiser for the Playhouse. The evening includes music by the All Stars Live band, drinks, a buffet dinner, costume contests, silent auction and tricks and treats, according to a news release.
"You're guaranteed to be tricked, treated, spooked and frightfully entertained!" co-chairwomen Deborah Mayhew and Heidi Miller said in a statement.
