Over ten years have passed since No Doubt released their last album, 2001's 'Rock Steady.' In the time since their hiatus, members of the group have gone on to work on different projects - most notably singer Gwen Stefani and her solo work as a "Hollaback Girl." The band reconvened for a summer tour in 2009 and have been working on their sixth studio album to be released this fall.

In the latest behind-the-scenes look at No Doubt in the studio, we see the band showcasing the prominent role horns will play on the new record. You know exactly when Stefani and her bandmates are in the building as horn players Gabe McNair and Stephen Bradley start performing 'The Imperial March' from 'Star Wars.' The trombone and trumpet elements will be featured heavily on 'Push and Shove,' which is due out September 25 through Interscope.

“Basically, all the sort of reggae-like-ish dance hall-y type songs have horns,” Stefani says in the video. “I’m surprised how many songs actually have horns on this record. I don’t even think the last album had this many.”

Judging by all the time No Doubt have been spending in the studio, the disc shouldn't take that much longer to complete. Bassist Tony Kanal says they have a few more finishing touches to add before 'Push and Pull' is ready for the masses.

"We've got a few more weeks of recording, tracking, we have vocals to do and we're just tweaking as we go," he says. "There's some work that we still have to do and then we're going to get into mixing hopefully in a few weeks. It's exciting. It's getting closer."
