When writing an album, there is an almost infinite number of factors that can influence the finished product. Morgan Henderson, bassist for the Seattle-based sass-core quintet the Blood Brothers, says however, there was one thing which drove the band while penning its most recent album, “Crimes,” released in 2004.

“I think it was just really wanting to write songs that were more fun to play live than our first album’s songs,” he says.

Anyone who has seen the band live since the release of “Crimes” can attest to its determination to turn live shows into all-out energy surges fueled by sugar-high-induced screams and jarring musicianship. Though the band’s onstage antics earned it a reputation as a sensational live band long before it began work on “Crimes,” Henderson says the new material lends itself better to the stage than the songs from the band’s previous two records, “Burn, Piano Island, Burn” and “March on Electric Children.”

“I think what it is, is that it has to do with bass,” he says. “In ‘Burn’ songs and ‘March on Electric Children’ songs, there’s a lot of parts in the song; there’s not a lot of time to tune a part, really. On the ‘Crimes’ album there’s much more bass; there’s less parts per song.”

With nearly a year on the road supporting the album, the band is currently touring with one of rock’s newest heavyweights – Coheed and Cambria. Henderson says the tour has the band consistently playing for some of its biggest shows.

“I’d say this is the biggest tour,” he says. “The AFI shows were probably bigger at some places, maybe, but it was only a couple of shows, where this is a whole tour.”

Being part of a major rock show has awarded the band certain luxuries to which it was previously unaccustomed. One such luxury is a tour bus, which Henderson says has given the band an even greater luxury – time.

“On this tour, I brought my bike with me,” he says. “What I like about the tour at this point is having all day to do whatever I want in different towns – so far it’s been great. When we’re in our van when we go on tour, we pretty much have to leave after the show and drive until about 2 or 3 in the morning, sleep a couple of hours, then drive to the next venue and get there around the time of the load in. So we don’t have time to go around the town or do anything. We’ve just had a lot of time on this tour to see our friends if we have them in whatever town.”

Though the band’s eclectic take on rock ‘n’ roll differs from Coheed and Cambria’s, Henderson says the band has been well-received by the crowd, despite a few instances where its been heckled.

Even if the band’s music is lost on some people, it is something the band is always pushing in new directions and are as challenging to create as they are to understand, Henderson says.

“I think it’s important for us to do that because I think that we’re a kind of band that writes from the kind of music we’re listening to at the time, like a lot of bands,” he says.

“For us, I think we feel the need to go beyond what we think we can do and try harder at doing that. For us it’s important to do that.”
