Dust off your portable radio and head over to Miami Beach’s Botanical Garden on Sunday to experience some serious sound art, and get your radio prepped for hurricane season, all in one. Subtropics.org, Miami’s long-lasting experimental music and sound art organization, is presenting “Emergency Radio Battery-Check,” in collaboration with Frozen Music and Talking Head Transmitters, which will transform the “acoustic topography” of the tropical environment.

Okay, what does this mean? It will go something like this. Grab your radio and tune it to AM 1610 — about a mile and a half away you will start to pick up the sounds being produced in the garden, a mixture of electronic, pre-recorded pieces, and live interviews. “We will be generating sounds designed to bring out the elements of the place,” says the ever-infectious Subtropics founder and sound musician Gustavo Matamoros.

“It will activate the ‘architecture’ of the space. With your radio on, you walk into the garden and start moving around with the sound, kind of like how you would experience hearing birds in a bush” from different positions. The artistic collaborative Talking Head Transmitters will be conducting interviews, adding to the 8-hour sound and feedback fest.

But first and foremost, don’t forget the radio. The event is also a community service, says Matamoros. “We’ll check the batteries, and provide new ones, just in time for hurricane season!” So get ready to engage all your senses for a Sunday in the park with sounds.

“Emergency Radio Battery-Check Nighttime Event,” 2-10 p.m., Sunday, May 23; free (with suggested donations for the batteries); Miami Beach Botanical Garden, 2000 Convention Center Dr., Miami Beach; 305-673-7256.
