Lisa is back with steel drum laden pop song in which her little voice peels and soars ambitiously. The notes tremble and dance in a gently epic way, reflecting the knock-it-to-the-bleachers swooping pop style of producer Dann Hume (Evermore). It’s an interesting step forward for Mitchell but, ironically, Spiritus lacks real spirit. There is something very white and very girlish about it, setting it leagues behind similar work by Sigur Rós or Bjork. Insipid middle-class musak.
