Elvis Costello and the Roots, SBTRKT, Kendrick Lamar and more in our weekly music recap

The typically reserved musician Aaron Jerome—better known as UK producer SBTRKT—bared a bit of himself this week with the surprise Twitter revealing of “IMO.” The unmixed and unmastered song is from new album recordings, and was posted in memory of his brother Daniel. In classic SBTRKT form, the video is a mysterious abstract work created by Lorenzo Durantini and the equally incognito design studio A Hidden Place, which is also responsible for designing the tribal mask SBTRKT is known to don during live performances—a facet so dear to his act it delayed his Terminal 5 show in NYC by nearly an hour after it went missing.
