Pink Floyd is the latest heavyweight act to premiere their catalog in the MP3 format through digital delivery firm 7digital.

With immediate effect, 7digital has released the legendary prog-rock band's entire albums repertoire as DRM-free downloads, become the first U.K.-based online store to do so.

London-based 7digital, which recently struck deals to release the EMI's Rolling Stones catalog and Beatle Ringo Starr's solo efforts, will launch the Pink Floyd albums with a limited-period price promotion.

Seminal sets such as "Animals," "Atom Heart Mother," and "Dark Side of the Moon," "Relics" and "Wish You Were Here" will initially be available to download at £5.49 ($11.14).

And works such as "Echoes - The Best of Pink Floyd," "Is There Anybody Out There?: The Wall Live 1980-81," "Pulse," and "The Wall" will initially be offered at £6.99 ($14.18).

In addition, 7digital will be the first to offer as MP3s in Britain the digitally-remastered re-release of debut album, "The Piper at the Gates of Dawn," which this year celebrates its 40th anniversary.

EMI reissued the album Aug. 27 in Europe by EMI and Sept. 3 in the United States. A deluxe three-CD edition contains stereo and mono mixes, plus other rare and unreleased material from the era. Packaging for the set has been designed by longtime Floyd collaborator Storm Thorgerson.
