Attracting a Mercury Prize-winning act such as Alt-J to Perth once in a blue moon would be considered lucky - twice in six months is virtually unheard of.
But that's precisely what will happen when this British four-piece follow a stunning set at St Jerome's Laneway Festival last month with a headline show at Challenge Stadium in July.
It will actually be the third time the group has been Down Under since October, which is some indication of the international demand for Alt-J's live shows since the release of debut LP An Awesome Wave last year.
That the considered music of hits such as Tessellate and Breezeblocks have found so much life beyond the studio comes as no small surprise to classically trained keyboardist Gus Unger-Hamilton. "I think we all thought our tracks might get a bit of indie critical attention in a chin-stroking way - 'Hmm, this stuff is quite interesting' - and then be consigned to the footnotes of British indie music," he says.
The relatively seamless transition from studio to stage is the result of rehearsing "three times a week, religiously", and there are times Unger-Hamilton is envious of acts that play shambolic, old-fashioned rock'n'roll.
"Sometimes I do think it would be nice if I didn't have to concentrate quite so much because a lot can go wrong in Alt-J songs; they're very intricate and fragile things," he notes wryly.
"There's not a lot to hide behind in our sound because we don't use any cymbals, the guitarists never play any chords, it's always picked stuff, so if you make a mistake it's going to stand out."
While An Awesome Wave scored the band a Mercury Prize it was ignored at the Brit Awards but Alt-J made their own waves at the ceremony by suggesting a collaboration with Dr Dre was on the wish list for album number two.
Unger-Hamilton plays down the idea, saying they are keen to revisit the low-key recording environment of their debut, which includes working with producer Charlie Andrew again.
"I think a lot of bands that have success for their first album think 'Let's turn on the money hose', and go to LA and do the whole big studio/big-name producer thing, but what we have is something that we really want to protect," he explains.
"We don't want to change anything because we don't want to ruin the magic, whatever it is."
At the risk of revealing how the magician pulls a rabbit out of the hat, Unger-Hamilton says songs typically start with singer Joe Newman bringing a skeletal song structure to him before introducing the idea to other members individually for their input.
He says his classical background generally adds musical logic to proceedings but, as one might expect of a genre-defying band such as Alt-J, logic isn't always a prerequisite.
The group has one song, titled 353, left over from the Awesome Wave sessions and some "really good ideas" to put towards a sophomore album and Unger-Hamilton says they all "hanker for the studio" once touring commitments are exhausted.
The keyboardist is hopeful that might see them writing in earnest before Christmas and hitting the studio to record early in the new year.
"But I wouldn't want you to quote me on that as the gospel truth but that's how I imagine things will go."Alt-J play Challenge Stadium on July 27 with tickets through Ticketmaster.
