The Avalanches will release new music in September.

The 'Frontier Psychiatrist' group are gearing up to put out a new single later this year, followed by a full album in 2014, according to

journalist Nosheen Iqbal, who claims she has heard some of the finished tracks.

She tweeted: ''Modular news scoop: New Avalanches album out in February 2014. 30 songs done and mixed. Heard some ystday + they sound exactly the same ... (sic)''

She then added: ''... But in a really GOOD way.''

The first Tweet has since been deleted.

The Avalanches' follow up to their hugely successful 2000 debut, 'Since I Left You', has long been planned, but very little in the way of music has surfaced.

Last year a demo version of one song, 'A Cowboy Overflow of the Heart' appeared online, while a few weeks ago the band also released snippets of two tracks to be included on a 'King Kong' musical soundtrack.

In 2007, the Australian band - Robbie Chater, Tony Diblasi

and Darren Seltmann - promised the album would be ready soon, writing on their website: ''It's real, it exists, and you know we wouldn't be serving anything up unless it was gonna give you that same special feeling that 'Since I Left You' has.

''Funnily enough its ended up sounding like the next logical step to since, we just had to go around in a big circle to get back to where we belong.''

The Avalanches website is offline, with a message saying to check back in coming months for ''special announcements''.
