Boston leader Tom Scholz tells Billboard.com he hopes to finish recording the band's next studio album after its summer tour and have it out "just after the first of the year."

Scholz says the album -- Boston's first since 2002's "Corporate America" -- is a mix of "really straightforward rock 'n' roll songs and some things that are pretty esoteric.

"When I first started," he continues, "I was doing music that had pretty simple themes. Then as I got into 'Third Stage' and 'Walk On' I got a little more technical and a little more involved, more complicated. In this one I'm trying to do both."

The new album will also include several songs from "Corporate America" that Scholz is remixing, rearranging and, in some cases, completely re-recording -- including the title track, "You Gave Up on Love" and "Someone."

"'Corporate America' was a really poor seller," Scholz acknowledges. "Very few people have heard it. I'd like to give some of these songs another chance to be heard."

 
Brad Delp, whose 2007 suicide "completely derailed" Scholz, appears on a couple of tracks on the new album.

Scholz says he felt "very weird" about playing Boston music without Delp at a tribute show last August, but has grown more comfortable with the idea during rehearsals for the summer tour with former Stryper singer Michael Sweet and Tommy DeCarlo, a fan Scholz discovered via a Delp tribute DeCarlo posted to YouTube.

"Brad was the most amazing musician [and] singer I've ever known. There's nobody on the face of this Earth that could replace him and do what he did," Scholz says. "But I have to say that these two guys, Michael and Tommy, do a really impressive job of performing these songs live.

"So it seemed wrong not to take it back out, and there were an awful lot of people out there that don't want to hear Boston go away," he adds.

Boston's tour kicks off June 6 in Thunder Bay, Ontario. Scholz has prepared a revised version of the group's "Greatest Hits" album to coincide with the tour.
