According to the band's Facebook page, the new edition will feature "new stereo mixes, a previously unheard version of 'From The Beginning' and a new 5.1 mix courtesy of King Crimson's Jakko Jakszyk."

The first disc of the limited edition set will feature a remastered version of the original album, the second disc will feature alternative mixes and the third disc will be "a surround sound DVD Audio disc produced by Jakko Jakszyk," according to Merch Now.

According to the band's posting, the new deluxe edition will be released in North America on June 30th and on April 27th in Europe. Amazon is taking pre-orders for the import here and MerchNow is taking preorders for the domestic version here.

Here is the product description: "'Trilogy', produced by Greg Lake was ELP's triumphant 3rd album complete with the cover art designed by the legendary Hipgnosis. Typical of ELP, 'Trilogy' covers a broad musical landscape from the ever-impressive display of virtuosity on the often-live highlight Hoedown, the softer delicate composition From The Beginning, and displaying their sense of humour on The Sheriff. Ambitious and often other worldly; If ever there was an album that showed ELP at their fullest and finest, 'Trilogy' was the band's moment of magnificence."
