With Celestial Weather, the focus of trumpeter and composer Wadada Leo Smith's collaboration with bassist and composer John Lindberg shifts to open duo improvisation, something they have often done in live performances but never before on a recording. The album opens with Smith's composition dedicated to the great, late AACM bassist Malachi Favors Maghostut and closes with Lindberg's "Feathers and Earth". The five-part suite that gives the collection it's name, "Celestial Weather Suite", was spontaneously created in the studio.
