The members of the Florida heavy metal group Trivium knew they were getting a kindred spirit when they asked Disturbed/Device frontman David Draiman to produce their sixth album, "Vengeance Falls."

But frontman Matt Heafy says the quartet got even more than it expected.

"He's the most hands-on producer we ever had," says Heafy, 27. "He's a singer and frontman and songwriter and live performer himself, so he knows how to develop vocals, songs, guitars, bass...everything. We've never had a producer that hands-on. He was an unbelievable vocal coach, which was no surprise, but he could also get an amazing drum sound and make everything else work. It was a great experience for us."

Heafy and company first met Draiman in 2005 and they've remained friends ever since, and he asked to produce their next album after complimenting Trivium's growth on "In Waves." Heafy calls "Vengeance Falls," which Trivium recorded in Draiman's current home of Austin, Texas, and is due out Oct. 15, "an angry record, inspired by personal, political and cultural concerns, and he says Draiman was key in helping to make the album's 10 songs (13 on the bonus edition) be the best they could.

"He really helped me deliver the kind of message I was trying to deliver, lyrically," Heafy explains. "If I had a song that didn't have a fully realized lyrical vision, he would encourage me to rewrite a section or the entire song and insure that everything that was there lyrically was benefiting the message of the song.

"We've never had a producer who could do that. Others maybe suggested we change a line here or there or substitute a cooler word, but no one's ever really been right on top of really driving the point of what I was trying to say in a song. I think I'll love these songs forever because of that."
