The fourth Tune-Yards album bears more electronics and dance beats than its predecessors, but Merrill Garbus' combination of sociopolitical savvy, outside-the-box creativity, and giddily infectious enthusiasm remains. While the R&B inflections and late-night club vibe of "Heart Attack" may represent something of a stylistic shift, the electronic beats of "Private Life" are sprinkled with the kind of world-music influences and playground-chant cadences that have been part of Tune-Yards' tool kit for a while. And the minimalist, dub-like feel of the haunting "Home" comes off as organic as anything Garbus has done.
