As a name, Iowa City band An Evening is brand new to the music scene. As musicians, Matt Grusha, Russell Karloss and Don Curtis are veterans.

Prior to the band’s creation last August, each member of An Evening was involved with another band. Grusha says he and Karloss have played in various bands throughout the years.

“Russell and I have been playing in numerous bands since about four years ago when we both went to Iowa State,” Grusha says.

“We both played with The Envy Corps for a few months, and then we quit and started this band.”

In An Evening, distinct band positions are unheard of. Grusha says the parts between himself and Karloss are split right down the middle.

“It’s pretty much 50-50,” Grusha says.

“We each write about half of the songs, we each play guitar on about half the songs, and we each play bass on about half of the songs.”

Grusha says it’s the same on vocals, too.

Curtis, who previously played with Poison Control Center, is drumming for An Evening only on a temporary basis.

While fans have heard each member of the band individually, they have not heard the members working together to create something Grusha calls “indefinable.”

“Honestly, I don’t have any idea [how to explain the band’s style],” Grusha says. “I’ve tried to have people help me out and tell me, but nobody seems to be able to describe it.”

While Grusha says he can’t classify the actual style of the band’s music, he can describe the techniques the group uses to try to pull away from common musical methods.

“We sort of de-emphasize the whole idea of overt hooks and melody,” Grusha says.

“I think our songs are catchy, but you wouldn’t find yourself humming the tunes when walking around.”

An Evening is working hard to get its music out and heard by fans.

“Right now we’re negotiating with a couple of producers to do an EP,” Grusha says. “We’re hoping to get into the studio early- to mid-spring and get our recording done.”

An Evening will perform its first official show Saturday at Bali Satay House, 2424 Lincoln Way, alongside local acts Organ Donor and Steps. The night’s show is part of a series of performances called Saturdays Rock, which will take place for five Saturdays in a row with three bands performing each night. Jim Schloemer, Saturdays Rock coordinator, says the crowd will have a good reaction to An Evening because the audience will be prepared for its sound.

“It’s going to be an Organ Donor crowd, so it’s going to be an audience that will already probably be pretty receptive to their style of music,” Schloemer says.

“In all the time I’ve known Grusha, he’s never been in a bad band, so I’m sure they’ll be a great band and everyone will be really impressed with them.”

Grusha says he doesn’t know what the crowd’s reaction to his band will be, but he knows they will be surprised.

“I think people are going to be kind of surprised at what they hear,” Grusha says.

“We’ve played in more pop-oriented bands before, and this is really kind of our attempt to get away from that and create a new kind of music based more on texture and harmony.”
