GREENE – As Tom Rodrigue warmed up on the electric bass – rumbling through the old Pink Floyd riff on “Money” – something jingled in an adjacent room.

“Oh, we’re going to be rattling a lot of things,” band mate Jeff Beam said with a grin. The teen musicians are accustomed to rehearsing in the barn of Beam’s farmhouse. However, temperatures in the 40s have forced them indoors, into his parents’ living room.

Rodrigue set up between a pair of recliners, slinging the bass over his shoulder. It hung from a guitar strap that resembled a seat belt from a 1970s Chevy, complete with a shiny, working buckle.

Beam stood a few feet away, setting an amp and a spare guitar on the couch.

Chris Hill sat behind a drum set in the corner, beneath a shelf of delicate, inch-tall knickknacks.

“What should we start with?” Beam asked.

“Just start playing something,” replied Hill.

A moment later, the trio launched into one of their own compositions, “George Russell.” About a serial killer from Seattle, it’s a rapacious rock ‘n roll song.

It’s also surprisingly polished for a trio whose youngest member can’t yet drive.

All three members of Specter are students at Leavitt Area High School in Turner. Rodrigue is 17 and a senior. Beam, also 17, is a junior. As big as the other two, Hill is 14 and a freshman.

They’re a serious bunch. All have been playing for years. Hill has been drumming since he was 4 years old.

“He’s the youngest, but he’s been playing the longest,” said Beam, who, like the others, grew up on classic rock music, particularly the Beatles.

“They brought me up in the right way,” Beam said of his parents, Deborah and Steve.

The sound of 1960s and ’70s rock ‘n roll comes through in the music, which has now spread onto their second CD, titled “Every Strength in My Body.”

They released the self-produced CD on Oct. 29. Copies are being sold at Bull Moose Music in Lewiston. Each of the 11 tracks was written by either Beam or Rodrigue.

Their first, a self-titled CD, was recorded in the upstairs kitchen of Beam’s house. The second was done at Soundhole Recording in Saco. On the first night the new CD went on sale, 75 of the initial 100 copies sold.

Is it a first step toward fame and riches?

The trio isn’t thinking that way. They’re trying to play as often as they can, at least twice a month.

“We just want to be respected locally,” Beam said.
