Whenever one or more members of a band announce they are going their separate ways, 'creative differences' is nearly always the official line trotted out, like some music-biz version of the old 'It's not you, it's me' break-up cliche.
Queensland outfit the Butterfly Effect is the latest to fall foul of differing artistic vision. After three-and-a-half years spent trying to write a follow-up album to 2008's Final Conversation of Kings, singer Clint Boge recently announced he was leaving the rock mainstays after more than a decade, leaving drummer Ben Hall, guitarist Kurt Goedhart and bassist Glenn Esmond to continue without him.
"Something had to give because we weren't getting anywhere writing this next record," Hall says from his Brisbane home.
"I think he felt he was selling his soul, and we felt we were just pushing him into trying different things and to be professional in his approach.
"We just weren't getting anywhere at all, and after three-and-a-half years you've just got to say, 'Well life's catching up with me now, I really need to work out what the fuck's going on here'."
Hall admits Boge's increased focus on his side-project, A Thousand Needles in Red, was also a cause of friction between band and singer.
"He'd get a bit like, 'Well in A Thousand Needles I call all the shots'.
"And it's like, 'Well, that's great, but this is a very successful band and the other band's a side project, we need you to work out how you're going to achieve bigger and better things with this band'.
"Eventually, we couldn't reach a compromise on that."
That said, Hall is quick to make clear any bitterness towards each other is now in the past.
And, much like a couple who remain cordial with one another for the sake of the kids, Hall, Esmond and Goedhart re-teamed with Boge for one last lap of the nation for their fans.
After returning home from the tour, which saw them hit WA earlier this month, the trio will now begin looking for a new vocalist in earnest and continue on under the Butterfly Effect moniker.
"Initially I thought we couldn't keep the name," Hall says.
"But then I thought about it, and to start again when there are three of us still in the band is a bit of a waste of the 11 years we spent building this brand.
"We spent five years in a touring van; I don't think at 30, 31 years of age we could really embark on that again. So it seems the best option for the three of us is to still be the Butterfly Effect."
While the long-term future seems planned out for all involved, given the emotionally charged circumstances, Hall admits there were some doubts as to whether the four could make I through the tour without imploding completely.
But, after a final farewell show at the Hi-Fi Bar in Melbourne, the group made it through unscathed and ensured their years of hard work together was signed off on an appropriately positive note before the next chapter in their respective lives.
"It's been nice to just rehearse the old songs without the pressure of having to create together," Hall says.
"Last time we were in a room with Clint we were fighting about things, so it's really good to be relaxed and just be able to enjoy what we’ve created over the past ten years."
