The first Orb album was entirely new when it appeared: a low-key dance record, with echoes and swells more than up-front tunes, stoner-level dub bass, and all sorts of samples and sounds--seagulls, film clips, astronaut voices, bits of disco--fluttering through the mix like hallucinations. Essentially a techno album for tired dancers, it's held up nicely over time, thanks to its intricate, dreamy sonics. Beyond the classic "Little Fluffy Clouds"--a set of interlocking synth hooks and loping percussion, held together by a cut-up sample of Rickie Lee Jones talking about the skies of her youth--there are lots of mellow delights here, particularly the blissful reggae groove "Perpetual Dawn." --Douglas Wolk
