The first official set of sales statistics for Radiohead's pioneering album 'In Rainbows' will be revealed later today (October 15th).

Warner Chappell, the publishing company who controlled all digital rights for the album on behalf of the band, are due to address a conference at the Iceland Airwaves Festival.

They are expected to announce that the album, originally made available for fans in October 2007 via an online honesty-box, earned more money before its physical release in December 2007 than Radiohead's 2003 predecessor 'Hail To The Thief' did in total.

Radiohead became the first band to allow music fans to name how much they paid for an album 'In Rainbows'.

Although Gigwise understands 1.2million copies of the record were downloaded in the opening day, today's report, previewed by Music Ally, doesn't specify the total sales, nor does it reveal the average price people paid for the album.

However, Jane Dyball, head of business affairs at Warner Chappell, will tell the conference later that the band's management company monitored the album's digital release daily, and were prepared the end the honesty box if the average price fell to low.

According to some reports, most fans still downloaded the album via BiTorrent websites.

It also states that Radiohead sold 100,000 copies of the special 'In Rainbows' box set. The album's physical release has so far sold 1.2million copies worldwide.

Stay tuned to Gigwise for all the latest information on the full report.
