This celebration of the British ambient-dance group's first 10 years is one for all electronic tastes. Whether you like your beats hard and fast or slow and gentle, U.F. Off has something for everyone, with each of the album's 12 compositions wrapped generously in the Orb's uniquely dubbed-out style. Orb aficionados will enjoy some new mixes of old favorites, such as "Little Fluffy Clouds" by LFC and "A Huge Ever Growing Brain..." by Orbital, while newcomers will be drawn by the timeless sunrise aura of "Blue Room" and "Pi (Part 1)." However, it is during the pulsating reggae throb of "Perpetual Dawn (Solar Youth Mix)" and the metronomic trance-floor classic "Assassin" that the Orb's richest identity shines. The first 15,000 copies come with a 12-song bonus disc containing further riches, rarities, and previously unreleased recordings. --Steffan Chirazi
