Raw and sweet like a mango on a summer day, Blue King Brown’s debut finds Natalie Pa’apa’a’s seductive vocals backed by the slinky, tropical grooves of a world-class crew of musicians. “Water” is a hip-hop- and jazz-infused gem that packs an environmental message, while “Come and Check Your Head” is a full-on Latin and soul throwdown. The title track sets its righteous message to an old-school reggae groove, and the traditional islander choir on “Samoa’s Song” adds local flavor.
