Jazz-rock combo Sea Level was formed in 1976 by keyboardist Chuck Leavell, bassist Lamar Williams, and drummer Jai Johanny "Jaimoe" Johanson following their exit from the Allman Brothers Band; guitarist Jimmy Nalls completed the original lineup, which in 1977 issued its self-titled debut LP on the Capricorn label. Honing its distinctive marriage of rock, blues, and jazz through relentless touring, the group returned to the studio with an expanded lineup including vocalist/saxophonist/keyboardist Randall Bramblett, guitarist Davis Causey, and drummer George Weaver to cut Cats on the Coast, also released in 1977, followed in 1978 by On the Edge featuring Paul McCartney & Wings drummer Joe English; although Jaimoe had returned to the Allmans, Sea Level recorded two more albums - 1979's Long Walk on a Short Pier for Capricorn (finally released in the U.S. in 1998) and 1980's Ball Room for Arista - before dissolving.

With a rich academic and performing background in jazz and classical music, composer/multi-instrumentalist Bill Douglas brings an experienced, creative approach to his playing and compositions. On Circle of Moons, Bill Douglas returns with 13 compositions imbued with his melodic versatility and sensitivity. This album delves deeper into the Celtic foundations of Douglas' music, expressed through dreamy synth textures as well as bassoon, flute, cello, English horn, and piano accents. Adding to the romantic, evocative atmosphere of Circle of Moons are the Boulder-based Ars Nova singers, whose charged harmonies on "Heaven Is a Wild Flower" give the poetic sentiments of William Blake a new, exultant setting. Circle of Moons brings emotion and technology together for an innovative and appealing interpretation of Celtic music on songs like the title track, "Sweet Dancer," "Highstep," and "Azure."
