The lineup isn’t due to drop until tomorrow, but with the likes of Big Day Out and Soundwave reaching the end of their 2013 festival lineup announcements, and organisers for St. Jerome’s Laneway Festival last week beginning to tease their own “mega dream lineup” for next year’s iteration, it was only a matter of time that some acts for Summadayze were leaked.

And that time, apparently, is now. The first act ‘leaked’ for the 2013 lineup is none other than M.I.A , who has a new album coming out later this year – just in time for the summer festival season.

The leak gained steam from the promoters themselves, Future Entertainment, who posted an extract from a Gold Coast Bulletin article claiming M.I.A would be on the bill.

“If you believe everything you read in all the national paper today it looks like M.I.A. will be making an appearance at Summadayze and Summafieldayze!”, the promoters wrote on Facebook.

So who else can we expect on the lineup? Well, there’s also a teaser for Summadayze 2013 has popped up on the festival’s Facebook and website. A short forty second montage filled with suitably sunstreaked bodies, bright colours, squiggly animations and more than few attractive girls and guys with tousled hair. So far, so promo.

The interesting part, and what could very well be a clue to the first of the 2013 Summadayze lineup, is the soundtrack. Namely, ‘The Boxer” from beat boffins, The Chemical Brothers, the single – featuring the Charlatans singer, Tim Burgess – taken from the band’s 2005 album Push The Button.

It’s of course too early to jump the gun and say that The Chemical Brothers will be headlining, but they’re certainly due for their regular visit to Australian shores. Given that it was Future Entertainment who brought Tom Rowlands and Ed Simons’ banging live show Down Under in March last year, they’ve certainly got the ability to do it again for a 2013 slot.

It might be a stretch to suggest that we can expect Tim Burgess’ outfit as well, but given Future Entertainment’s fondness for UK acts, it might not seem so far-fetched after all.

Long story short, we have little to go on, but when the first lineup announcement does drop this Thursday 13th September, we won’t be too surprised if the Chemical Brothers top the list. After all,remember the Parklife promo that featured Passion Pit? Well, the electropop group ended up appearing at Parklife 2012.

What we can expect, if last year’s mix of acts is anything to go by – featuring the likes of Snoop Dogg, Scissor Sisters and the recently defunct Pendulum – is a strong mix of acts that’ll appeal to both commercial and alternative audiences.
