LITTLE FALLS — It’s a block party Saturday, May 20, at the first-ever Powerhouse Rock Festival at Rock Valley Brewing Co., 56 West Mill St. The free event will feature three local rock bands on two different stages, multiple food vendors, and, of course, craft beer.

Doors open at noon. Music starts at 2 p.m. with 90s and modern alternative rockers Rev-D and continues to 11 p.m. with classic rockers Walrus on stage at 5 p.m. and Pink Floyd tribute band Dark Sarcasm at 8 p.m.

“This is the inaugural Powerhouse Festival in Little Falls,” said Bob Bivona, the founder and lead guitarist of Dark Sarcasm.

“It was the brainchild of Mark Regan, who envisioned this event as a way to bring people in for a full day of great music, food and fun.”

Dark Sarcasm started in 2012 and is an eight-piece tribute focusing on performing an authentic Pink Floyd experience with songs from their most famous albums including “Dark Side of the Moon,” “The Wall,” “Wish You Were Here,” “Animals” and more. Plus the shows come complete with full production, and an eye stunning light show as well, Bivona said.

“The band is definitely the sum of all its parts,” Bivona said. “We are lucky to have eight talented people with the same passion and direction.”

Walrus singer Sydney Pinto said she is excited about performing at the new Powerhouse Rock Festival. Pinto said Walrus is a high-energy band, also featuring two lead guitarists, Ronnie Dark and David DiNiro, bassist Howard Gersony and drummer Jeff Mosher.

She said Walrus brings something a bit different to the table.

“With four singers in the band we have some nice vocals and harmonies,” Pinto said. “I personally love to sing songs from artists such as Grace Slick, Stevie Nicks and Bonnie Raitt, amongst many others. Having other singers in the band lets us do a wide variety of great music! Tunes from Tom Petty, The Who, Lenny Kravitz, The Beatles and even Metallica. I love the variety of songs we have chosen for our audience.”

They will bring to the stage high energy and lots of fun and she promises the audience will not be disappointed.

REV-D reported to its Facebook fans recently they had a “great rehearsal this afternoon with some new songs added for the Powerhouse Rock Festival ... just wait until you hear.”

“As we have for the past two-plus years, we will be bringing a high-energy show full of 90s alternative and modern music,” promised REV-D bassist and backing vocalist Tom Papura.

“We have literally played the brewery about 7 or 8 times now and always have a good crowd that comes to see us.”

He is joined in REV-D by Eric Scalise on lead vocals, Mike Nawrot on guitar and Little Falls native Phil Scarano on drums.

Guests are asked to also bring canned goods and nonperishable donations to benefit the Little Falls Food Pantry.

They should also bring their own lawn chairs.
