“Her Eyes Are Blue and Sometimes Gray” is a song from the Chicago Soul Jazz Collective’s upcoming second album, It Takes a Spark to Start a Fire, due out October 30. The song features a contribution from trumpeter Nicholas Payton and the sextet’s saxophonist/co-leader John Fournier explains that while at first, the band played it at a faster-pace, it was when they played it at a much slower tempo that the composition “revealed itself to be a haunting and wistful composition … It had a mesmerizing effect on us.”
