The term “sophomore slump” doesn’t faze Via Audio.

Rather, the Brooklyn-based indie-pop quartet confidently released its second album, Animalore, as a “melting pot” of eccentric and varied sound, following its critically acclaimed 2007 début, Say Something.

Via Audio will perform at the Mill, 120 E. Burlington St., at 9 p.m. today, with opening guests Pattern Is Movement and Oh Kuso. Admission is $8.

The band formed in 2003, while original members Jessica Martins (vocals, keyboards, guitar), Dan Molad (vocals, guitar, drums), David Lizmi (bass), and Tom Deis (vocals, guitar) attended school at Berklee College of Music, in Boston. Adam Sturtevant replaced Molad in 2007. The formation of the band, Lizmi said, was an organic process that “magically” came together.

“Dan and I were looking to start a band,” Lizmi said. “Jessica seemed like someone lovely to play music with, and I was playing with Tom in jam sessions, and he was a wonderful player.”

Though Via Audio can be described as melodic indie pop, the band is known for its tendency to experiment with “genre jumping.” Because each of the band members comes from different backgrounds, Via Audio’s sound consists of what Lizmi termed a hodgepodge of influences. With inspiration coming from grunge, electro, dance pop, and more, it is difficult to come up with a better term. Each member’s open appreciation for all musical styles is what has allowed them to come to some sort of creative agreement.

With two albums under its belt, Via Audio has seen maturation in its songwriting and recording. The experience created a much closer relationship among the members, resulting in a more cohesive product. The new album, Animalore, even included former drummer Molad as part of the recording process, a testament to Via Audio’s commitment to creative unity.

“A song may follow a similar path to the demo, or it may go in a completely different direction,” Lizmi said. “We all bring our ideas to the table to form the Via Audio sound as opposed to only one member’s particular sound.”

Jim Eno, the drummer for the band Spoon, produced both Via Audio albums and has become good friends with the band members. Eno’s mastery of the boards was yet another part of the equation of Via Audio’s creative endeavors.

“He’s really proficient and knows his way around to get a great sound,” Lizmi said. “He’s a great producer, and that’s the bottom line.”

This cohesion noted by Lizmi is clearly visible to people outside of Via Audio’s creative circle. Julian Guzman, a longtime fan of Via Audio, first became acquainted with the band in 2004, attending a show at the Wentworth Institute of Technology, in Boston, where he studied at the time. Guzman said Via Audio’s “unabashed willingness to take risks with its sound and produce music that is full of life and energy” that draws him to the band’s music.

The energy Guzman speaks of transfers from record to stage, where Via Audio makes it a goal to get everyone in the audience moving. The band “isn’t big on crossing your arms and just sitting back” to watch a show; the members prefer jumping, clapping, and singing along.

“Hopefully, they’ll take away a memorable night, with great music, great musicianship, and new friends,” Lizmi said. “Something that will make their day a little bit brighter.”
