It's often referred to as "needle-drop" sound - a term reserved for tribute bands who can replicate the same sound a fan would hear when they drop the needle to the record at home.
For a group paying tribute to the iconic Led Zeppelin - arguably the masters of guitar and vocal overdubbing - that can be especially tricky.
Enter Get the Led Out. The group, which includes lead singer Paul Sinclair, Paul Hammond, Jimmy Marchiano, Billy Childs, Adam Ferraioli and Andrew Lipke, aims to give Zeppelin fans a taste of the music as it was originally heard.
To do that live, Sinclair explains, requires six guys to Led Zeppelin's original four.
"The people who have never seen our show are kind of confused," says Sinclair, speaking from his home in Bluebell, Pa. "When people (are surprised to) see we've got six guys on the stage … I just have to laugh. Led Zeppelin never got on stage and performed those songs the way that they recorded it. They had a very different sound live."
Get the Led Out will perform at the Levoy Theatre in Millville 8 p.m. Saturday, May 11. Sinclair says fans can expect to be transported back in time.
"It's just the way they grew up listening to it," says Sinclair, a BMI-affiliated songwriter who also owns Fat City Studios in Philadelphia. "That's the one thing people can expect from our show. There's such competition out there - and God bless everybody out there doing it - but it's the one thing that separates us from the rest (of the tribute bands)."
Since forming, the band has developed a cult following of Zeppelin fans. Sinclair, who has released studio albums on his own and continues to write original songs, admits he never envisioned himself in a tribute group, but he's certainly not complaining.
"This gig is my dream come true," says Sinclair, 48. "Most of the guys (in the band) are older. We've all had various levels of careers. We all grew up listening to Led Zeppelin, cutting our teeth on Led Zeppelin. In my personal case, Steven Tyler and Robert Plant are really the reason I sing, so I model my style after them."
The band started simply enough. Sinclair and Hammond, who are longtime friends, would sing Led Zeppelin songs with a house band at a local bar.
"We found ourselves doing a local bar gig, literally for peanuts, just once a month," Sinclair says. "I got a call from some other area musicians looking to put together a Zeppelin show. I was unaware of the tribute world. I didn't know what kind of market there was for it, and I certainly wasn't interested in doing the impersonator thing."
So the plan, Sinclair says, was not to imitate Led Zeppelin by dressing in costumes. Instead, the group would work to recreate the Zeppelin studio sound on stage.
"Not only did I not envision myself doing this type of thing - but as a really young kid trying to get into being a rock 'n' roll musician, it was one of those things you looked down upon," Sinclair says. "You don't want to do covers, you always want to do your own material. But, I could not be happier."
Sinclair recalls the band's first official show in December 2004. After preparing to play a small gig at a Delaware County, Pa., bar, Sinclair's manager told them they now had a new gig - Penn's Peak at Jim Thorpe Resort in the Poconos, a venue that seats 1,700 people.
Sinclair braced himself for what would surely be an embarrassing night, playing to a mostly empty room. But as they began to play on stage, he recalls, something happened. People heard the sound and started walking in.
"There were 1,000 people in the room for our very first show," Sinclair says. "I was blown away. This is where I started to see what this project could become."
The band performed at the same venue for a sell-out crowd just a few weeks ago. For Sinclair, the band has come full circle.
"Because we all grew up with the music, we come at it with a different perspective," Sinclair says. "(Younger fans) didn't live it. This is the soundtrack to my life. I have more of an attachment to it. These guys were mythic heroes when we were kids, and still a viable band. This was the music that was playing. It's very personal."
There is a niche to be filled with this type of music, Sinclair says - especially when the artists who performed the original music are not touring.
"We're really trying to live the music and trying to get that close to somebody else's performance," Sinclair says. "Not just 'Oh, you hit the right notes,' … but all the ways they hit the notes. It's an impossible feat, which is fine, but every performance is an opportunity to get that much closer."
