Although known to fans as "the quiet Beatle," George Harrison left behind a wealth of legendary albums upon his death in 2001. Fans have also been exposed to a number of unreleased demo tracks over the years through unofficial releases, including solo demos recorded in the waning days of the Beatles as he transitioned to working on his debut album, 'All Things Must Pass.'

Some of those demos, along with other rarities, will see a U.S. release on May 1 with the release of 'Early Takes Vol. 1,' a set of ten songs featured in Martin Scorcese's October 2011 documentary on Harrison, 'Living In The Material World.' Both DVD and blu-ray editions of the documentary are due for release on the same day.

Many of these tracks appear similar to those released on the famous Beatle bootleg 'Beware of ABCKO,' at least one of which also turned up on the Beatles' 'Anthology 3' release. Harrison's collaborations with Bob Dylan are also spotlighted, including an early take of their co-written track 'I'd Have You Anytime' and Harrison's demo of Dylan's 'Mama You Been On My Mind.' Rarities from later albums such as 'Thirty Three and 1/3' and 'Living in the Material World' also appear on the collection.

The set will be available in both vinyl and CD incarnations and should be available for pre-order soon from Amazon. Harrison fans with iPads will also want to check out the singer-songwriter's guitar collection in the exclusive 'The Guitar Collection: George Harrison' app, available through iTunes.
