Apple made the new £2.99 GarageBand music-creation app available last month to coincide with the launch of the iPad 2. The band have now made the Underwear Party album available via iTunes.
Singer Max 'Bunny' Sparber told Wired, "I see [the GarageBand app] as an everything-combined-into-one package. Both new musicians and professional musicians are going to be very surprised with what they can do with it [...] Making an album even a year ago costs thousands of dollars. This is a huge transformation. It's part of the ongoing democratisation where the tools have become inexpensive and that's a very exciting prospect."
Last December, Gorillaz made their new album, The Fall, available via their official website to fan club members, claiming it had been recorded by Damon Albarn using just iPad apps while on tour.
Meanwhile, EMI has created a remix iPhone app for the reissue of David Bowie's Golden Years EP on June 6.
Fans will have access to eight stems from the song, bounced down from the original 16 tracks, to remix and share online. They can also shake their iPhone to create a random mix of the track.
This follows the release of Bowie's Space Oddity remix app last year.
