Music in the Liquid Mind series changes little from one recording to the next — good news for contented fans of the long-running bliss-out series created by keyboardist/composer Chuck Wild. The former Missing Persons keyboardist and studio colleague of famed producer Ken Scott (David Bowie, Supertramp) has evolved into a premier space-music specialist whose relaxing, gentle soundscapes artfully evoke the softer side of the cosmos. His eighth Liquid Mind installment, subtitled Sleep, is a lovely, slo-mo spacewalk through serene, gravity-free realms that consistently yields a sustained sense of well-being and calm. Deserving of a spot at the head table with ambient music's most sophisticated sound designers, Wild creates slowly unfolding, universe-at-rest textures using few of the supplemental sonic dimensions (space winds, angelic voices) often employed by fellow stargazers Jonn Serrie and Jon Jenkins. And he sidesteps the small dramas and mysterious fractals that sometimes add a hint of uncertainty to the otherwise like-minded works of Brian Eno or Harold Budd. Happily, you'll hear no new-agey crystal bowls or plucked harps, either; just a warm, resonant, faintly classical glow skillfully designed for relaxation and peace. Pull up a cloud, lie back, and enjoy.
