But he insists it will be worth the wait.
DeCarlo has been with the band for four years, but took over the mic full-time last year following the departure of Michael Sweet.
He landed the job after writing a tribute song to classic-era frontman Brad Delp, who committed suicide in 2007.
Mainman Scholz has been working on the follow-up release to 2002′s Corporate America for several years. In 2011 he said it was “85percent complete” and rumours suggest it will see the light of day in 2013.
DeCarlo tells OnMilwaukee: “Unfortunately I don’t have a time frame on that. Tom’s quite a perfectionist when it comes to his sound and his music. It’s not always done in a timely fashion.
“But when it gets done, it’s fantastic. I’m with all the fans – I’m excited to hear it myself. Let’s keep our fingers crossed.”
Until then, DeCarlo finds himself looking for other work between Boston tours.
He explains: “I wasn’t a part of the early success of the band, so I don’t reap any of the benefits – residuals from records or anything.
“So when the band isn’t touring I have to find means to support myself.
“Fortunately, with this opportunity Tom gave me, a lot of those opportunities come through music. So I haven’t had to go back and punch a clock and work a 40-hour week. That’s been a true blessing.”
And the singer vows that, no matter how well things go in the future, he’ll remember the times he was uploading cover versions to his MySpace page.
“The Boston shows I went to in the mid-nineties, I had nosebleed seats,” he recalls. “I was out in the middle of nowhere. So I always make a conscious effort when I’m on stage to make some kind of contact with people who are way out there. I remember being out there.”
