Count live music among the amenities of Tybee Island. The third season of Third Thursdays, bringing free acoustic music to public places, for a nice little change o’pace, begins this week.

The first show features Jason Bible, the singer/songwriter from Savannah’s top country–rocking Americana band, the Train Wrecks. He’ll be in the roundout at the corner of Strand and Tybrisa (just a Frisbee’s throw from the pier and the beach) Thursday (Sept. 15) from 5 to 6 p.m.

The Old Folkers, with Hank Weisman of the Savannah Folk Music Society), will play Oct. 20 at The Lot at Tybee Oaks (here’s a quick GPS for you: It’s in the Huc–a–Poo’s parking lot).

Harry O’Donoghue, the Irish singer and songwriter who’s a fixture at Kevin Barry’s place on River Street, closes out the series Nov. 17 at the roundabout.

This week at the Ocean Exchange

The Savannah Ocean Exchange is in full swing. The series of events focusing on the world’s oceans and its problems – and the potential solutions to those problems – is taking place here because of Savannah’s unique coastal environment.

Check out the entire month’s worth of lectures, demonstrations, screenings, panels and other events at savannahoceanexchange.org.

Here’s the best of what’s on deck, general interest–wise, for this week and beyond:

Ocean Conservancy International Coastal Cleanup. Meet by the Tybee Pier Pavilion at 8 a.m. Sept. 17 to participate in a beach–wide trash pickup effort.

The U.S. Army Band gives a free one–hour concert at 7:30 p.m. Sept. 18 in Forsyth Park. Bring your lawn chairs.

Many of the SOA events aren’t for everybody, of course, but the public will surely get an environmental bang out of the annual Gray’s Reef Ocean Film Festival, Sept. 22–24.

On Sept. 24, ecologically–minded singer and musician Bob Zentz performs at 7 p.m. in the Trustees Theater, using a collection of homemade and “found” instruments.

The Ships of the Sea Museum has an Ocean Exchange project on Sept. 25, at which children can make pond yachts from models. Registration is required at (912) 232–1511.

“Oh Say Can You Sea Savannah”: There’ll be an Ocean Exchange–themed children’s art show inside the Tybee Post Theater Sept. 23–25; at the reception on the 25th, the Savannah Children’s Choir will perform (at 5 p.m.)

And now, this

• If you were disappointed that Lucinda Williams never made it our way, as was once announced during the summer, take heart: She’s got an Oct. 16 date at the Charleston Music Hall.

• Let’s all take note of the Sept. 23 show at Tantra Lounge: It’s a pirate–themed burlesque show (!) called “Naughty Nautical Nite,” and here’s the official description, upon which we could not improve: “Dame Darcy the banjo and singing saw sea shanty playing mermaid, as she brings you sexy sirens of burlesque, hot sailors, pirates, and goofballs of every variety, ribald sailor mouthed jokes and performance art.” Admission to the 9 p.m. show will be $3, but you’ll get $2 off if you come dressed in pirate garb.

• Tickets are now on sale for an Oct. 28 Savannah Civic Center concert featuring the O’Jays, with Charlie Wilson, the longtime Gap Band vocalist.
