The Police owed much of their sound to reggae, and JA artists return the favor on Spirits in the Material World, a comp of dancehall, lovers rock, and roots covers of Sting & Co.’s familiar tunes. No dyed-(blond)-in-the-wool Police fan or dreadlocked Rasta should be mad at Junior Reid’s take on “Synchronicity I,” Horace Andy’s cover of “Invisible Sun,” or Toots & the Maytals’ version of “De Doo Doo De Daa Daa Daa.” Sure, nothing can redeem the overly fluffy “Every Little Thing She Does Is Magic” (especially not UB40’s Ali Campbell) and Joan Osborne isn’t exactly Judy Mowatt, but Gregory Isaacs doing “So Lonely” needed to happen (even if it’s 20 years late).
