Brave Last Days is no more.

The Chicago-based band recently made the risky decision to change its name, and lead singer Billy O’Neill is quite positive the new nomenclature Oh My God will work.

O’Neill isn’t worried about the fact that a couple of band members have left and been replaced.

“We don’t feel it’s gonna damage our fanbase because we’re gonna be really thorough with sending out e-mails and mailing cards,” O’Neill said from his Chicago home.

Oh My God plays what O’Neill describes as “narrative eclective rock.”

“We struggled for a long time to come up with a one-liner to describe our music, and we didn’t really seem to fit into the correct phrase or niche,” O’Neill said.

The band draws from many styles of music and fuses it together into its own brand of rock, which seems to be the trend of many bands — a trend that breaches the boundaries of mainstream rock.

“We run the gambit stylistically,” he said. “At times we’re edgy and heavy, and other times we’re more along the lines of a band like Cake.”

Oh My God’s diverse musical style, along with the fact that O’Neill adds “narrative” in some of the songs, is where the band got its “eclectic” reputation.

“I sing the songs from a specific character,” he explained. “It’s theatrical in that sense.”

Oh My God draws inspiration from a wide array. O’Neill’s influences include Ani DiFranco and Billy Joel. He also calls Rage Against The Machine “one of the most intense bands out there right now.”

“I’m inspired by anything I sense to be authentic,” O’Neill said. “If somebody’s spilling it for real, then I can say, ‘Alright. Right on. I dig that.'”

O’Neill met drummer Patrick Marshall while in college. He then sought out a guitar player in a sort of non-traditional manner.

“We met the guitar player [Jimmy] the way that it’s most unlikely that you will ever meet a great, inspired, talented musician … through an ad.”

The band then went on to hire famed organist Johnny Iguana to round out its sound. Astonishingly, there is no bass guitar in the band because Iguana plays the bass part on the left end of the organ, while adding melodies with the upper keys.

O’Neill said Iguana, who recorded “Live at Buddy Guy’s Legends” on the Grammy-nominated album with Junior Wells, is an excellent addition to the band. He believes the sound of an organ in rock music will not be looked down upon at all.

“I think the world of rock music has an openness these days,” he said. “People are open to creative ways of playing rock music.”

When he isn’t involved with his band, O’Neill loves to get out and enjoy the arts on the stage or in the pages of a good book.

“I love theater and movies. The live performances are what turn me on. I would do just fine going around and seeing people play music, seeing theater and reading books all day.”

O’Neill is currently reading “Tropic of Cancer” by Henry Miller, but he said he just finished a remarkable piece of literature that inspired him greatly.

“I just read ‘Giovanni’s Room’ by James Baldwin, and I thought that was brilliant,” he said. “That actually moved me considerably. That guy was so in tune with what human beings felt.”

O’Neill finds gratification in writing his songs and finds tranquility addressing many virtuous issues.

“I guess sincerity and freedom inspire me. I’m inspired by somebody who is free of pretension and is expressing their natural disposition. When I see somebody that is free of self-consciousness, that is inspiring to me.”

O’Neill will have to set his books aside soon and concentrate on music as he and the band prepare to head into the studio to record an album in April.

The band will be working for three days with producer Chris Greene of Alien Sound in Chicago, who has also worked with trip-hopsters My Scarlet Life.

“Basically, we’re gonna go in, rip out a bunch of songs and see how it turns out,” O’Neill said.

He added he was very excited to work with Greene because they share the same goal for the album, which is capturing the band’s live energy.

Although Oh My God is starting out fresh with a new name and new faces, O’Neill would rather not focus on hitting it big anytime soon. He has a more down-to-earth approach for his band’s success.

“I know a lot of it is hit and miss. I think it’s dangerous to be too concerned with outcomes and results,” he said. “What will lead to success and what is success is enjoying the process, to be fully alive and fully enjoying the moment.”

Oh My God will open for My Scarlet Life Saturday at 9 p.m. at the Maintenance Shop. Tickets are $5 for students and $6 general admission.
