Assorted ramblings from the world of entertainment:

•   24 Hour Theatre returns to Trumbull New Theatre in Niles next weekend.

For the uninitiated, performers will show up at 7 p.m. June 9 at TNT, 5883 Youngstown Warren Road, with a short, prepared monologue to use for their auditions.

After auditions, writer-director teams will draft their casts. The actors get to go home and get a good night’s sleep while the writers stay up all night crafting a short script (about 10 to 15 minutes) for the actors.

The directors and actors return at 8 a.m. June 10 and have 11 hours to learn their lines, create blocking for the show and come up with the necessary costume and props for their script.

At 7 p.m. that evening — 24 hours after auditions started — they will perform those plays.

It can be a trial-by-fire for inexperienced performers, a taste of stage action for those whose schedules won’t let them commit to weeks of rehearsals and multiple weekends of performances or just a chance to perform at a time of year when many community theaters have ended their seasons and are taking a break for the summer.

There is a $10 participation fee, and admission to the performance is $10 at the door. For more information, go to TNT’s Facebook page.

•   Tickets are on sale now for a Noisy Fans Appreciation Concert July 1 at JR’z Pub in Austintown.

The evening celebrates the music of Noisy Mama / WhiteNoise, a hard rock staple in the Mahoning Valley in the 1980s that landed a record deal with ATCO Records in 1990.

The group’s major label debut, “Everybody Has One,” was released in 1991, the same year grunge shifted the music industry’s attention away from the kind of music that was Noisy Mama’s specialty.

The band was one and done at ATCO but remains a local favorite.

The July 1 show will feature original lead singer Paul Skowron and drummer Tommy Rich joined by Carl Infante, Billy Morris and Dougie Manross.

Tickets are $12 in advance and $16 at the door and are available online at paulskowron.com.

•   Over the years, I’ve seen some great shows at the Three Rivers Arts Festival in Pittsburgh.

On the downside, I had to deal with Pittsburgh traffic and parking, but that was more than offset by the cost of those shows — FREE.

Three Rivers Arts Festival has moved from Point State Park to the city’s Cultural District with most events in the area of Penn Avenue and Seventh Street.

That doesn’t make parking any better, but the event continues to bring in national acts for free outdoor performances.

This year’s lineup on the Dollar Bank Main Stage at the intersection of Fort Duquesne Boulevard and Stanwix Street, includes KT Tunstall on Friday, Galactic on Saturday, Rising Appalachia on Sunday, the Pittsburgh Symphony Orchestra on Monday, Lizz Wright on Tuesday, Red Baraat on Wednesday, Corinne Bailey Rae on June 8, Mo Lowda & the Humble on June 9, Chali 2na and Cut Chemist on June 10 and Taj Mahal Quartet on June 11.

Entertainment by many Pittsburgh-area music, theater and dance groups also is featured on multiple stage, and the centerpiece of the event is an artist market featuring artisans from around the country. Galleries in the Cultural District will have special exhibitions, and public art displays also are part of the event.

The artist market is open from noon to 8 p.m. daily. The festival closes at 9 p.m. each night, and main stage concerts start at 7:30 p.m.
