When a woman rips a guy's heart out of his chest, tosses it into a blender and presses "frappe," he either falls in love with his depression or does something practical with the pain -- just ask any emo fan. So when Diecast singer Paul Stoddard sat back and witnessed the recent collapse of his own relationship, one that had lasted more than four years, he took his pain and channeled it into his lyrics. The result, he said, is the Boston metalcore band's fourth LP, Internal Revolution, which is set to drop Tuesday.

"Any time you can take any emotion -- whether it's anger, sadness, even happiness -- if you can take that emotion and squeeze it for all its lifeblood, you're going to get amazing songs," Stoddard explained. "Initially I was toying with the idea of maybe doing a theme record this time around. But when it came time to start writing these songs, I had so much stuff inside that I wanted to get out and write about, I just said, 'Forget it -- I'm going with this.' "

Not that the inspiration behind his words will be blatantly obvious to the casual listener. But while Diecast's frontman uses some symbolism on the record, he didn't exploit it to make his point.

"I try not to hide things too much," he explained. "I think people can pretty much get the point of where I'm going with a lot of the songs. I don't want it to be too clear and come off cheesy: 'I loved her. She's gone. Boohoo.' I think you have to have some fun with it and be artistic with [music]. People will always identify with it in their own way."

Heartbreak aside, the road to Internal Revolution was riddled with numerous obstacles, Stoddard said. Within the last year, Diecast have lost -- and replaced -- two of their members, sidelining them for a spell from touring and recording the follow-up to 2004's Tearing Down Your Blue Skies. Drummer Jason Costa left in November, following a heated argument concerning Brendan Fraser's acting prowess, and in May, the band announced that bassist Jeremy Wooden, the band's only remaining original member, had split. Dennis Pavia and Brad Horion were later named as their respective replacements.

A scheduling conflict delayed the effort even further. The band had recruited producer Zeuss (Shadows Fall, Hatebreed) to helm Internal, but he had to pull out at the last minute. Instead, Diecast turned to Tearing Down's producer, Paul Trust.

"Jason was an absolutely incredible drummer," Stoddard said. "He was something Diecast had become known for, and so you tended to write songs that really showcased his abilities. And then you'd write good songs around that. But this time around, we started without a drummer, and we just wanted to write the best songs possible. We tried to eliminate all of the walls. We just wanted to make the best record we could, and get the best songs possible. We didn't want to set any boundaries, which is what the scene tends to do. If it makes sense, it will be there. If it doesn't make sense, we're going to replace it with something that does.

"I feel like my vocals have come a long way too," he continued. "We went the extra mile on this record, and I'm so excited about it. I'm ready to start writing and recording the next one, because we're in such a good zone and we're just connecting so well that I don't want to stop."

The album's theme comes through in several of Internal Revolution's tracks, but none more so than the first single, "Fade Away." Diecast recently shot a video for the tune in a vacant building in Brooklyn, New York, with director David Brodsky (God Forbid, the Red Chord).

"It has to deal with breakups, and everybody in the band was involved in different relationship scenarios," Stoddard explained. "I got to smash some windows and break through a wall like the Kool-Aid man. For my part, there's this woman on the other side of the glass, and I break through it to get to her. It's symbolic."

Diecast will spend much of next year on the road but have no concrete touring plans just yet. The band will play a semi-acoustic record-release gig at Newbury Comics in Nashua, New Hampshire, on Tuesday, and a headlining show in Bedford, New Hampshire, the following evening.

Really, what Stoddard wants is what most metal and hardcore bands want: an Ozzfest slot.

"I've been to every single Ozzfest, except for 2005's," he said. "For the last 10 years, I would go to that festival, and my dream has been to make it onto one of those stages. I'll feel like I've made it if that happens. We were up for it last year, but it didn't work out. But it would be great to do Ozzfest. That would be a dream come true, and we hope the stars align, and this time, it will be our turn."
