When Frank Ocean rains, he pours — both musically and in the way of indecipherable water imagery. After the lengthy wait for Ocean’s follow-up to Channel Orange resulted in not one but two new releases, Ocean is keeping up his prolific pace, now with a Calvin Harris and Migos collaboration. The song, “Slide,†is nominally a Harris track, though Ocean and Migos of course take the lead on the vocals, while Harris, Ocean, Offset, and Quavo all share writing credit. Also of note on the track listing is the line that “Frank Ocean appears courtesy of Frank Ocean,†confirming his post–Boys Don’t Cry status as a free agent. Give the electric “Slide†a listen below, boogie-woogie-woogie.
