Mutemath opens for 30 Seconds to Mars on Friday at the Fillmore Auditorium.

Mutemath’s got it all figured out.

The innovative alternative-rock band’s always coming up with new musical formulas. Mutemath’s run the gamut from electro to experimental pop sounds, and the group decided to take its music up a notch for its latest CD, Armistice.

The inventive band usually headlines shows, but this tour finds Mutemath opening for 30 Seconds to Mars, including the band’s Friday gig at the Fillmore Auditorium.

“We always get inspired to create new music,” lead singer/keyboardist Paul Meany said. “The idea is to continue to be inspired and write better music.

“Every time we make a record it becomes an exercise in songwriting. Then, all of a sudden, you strike gold and the whole record comes together. That’s how we made the last record.”

Mutemath’s self-titled debut came out in 2006. The band’s released several singles since the last CD came out, but the group had to dig deep for Armistice.

“It was a painful process to make this record,” Meany said. “We started writing and realized that it felt forced and uninspired. We hated everything and decided to start over.

“Then we stumbled upon this guitar riff and it immediately opened the floodgates. All of a sudden, we could feel a sense of what the record was about. We didn’t want to write in the shadow of our previous work — and I think we made a genuine record.”

Mutemath also decided to throw a producer into the mix. The band brought in studio pro Dennis Herring (Modest Mouse) to solidify Armistice’s songs.

The CD came out last fall, and the 50-minute record shows off the full range of Mutemath’s musical dynamics and songwriting skills.

“It was the first time we really got to indulge on a record,” Meany said. “We added some horns, so it wasn’t just a four-piece rock band. We tried some soundscaping and a minimalist approach, and we stripped down the songs.

“The CD has an intimate feeling, but we really pushed what we could do with guitars and keyboards. There was also a lot more writing as a band, because we wanted to write the songs from the ground up. It was an interesting experiment with the four of us.”

Mutemath has a wide base of fans, but the group decided to jump on the 30 Seconds to Mars tour.

“Sometimes we headline tours and sometimes we hop on other tours to get new fans,” Meany said. “It helps us move forward. 30 Seconds to Mars invited us on this tour and it seemed like it would be fun.

“It’s always a nice change to be a support band. There’s a little less pressure, too. You walk in with people staring at you and maybe not knowing who you are — and you have 40 minutes to turn that room into fans.

“That makes us a better band.”
