Playboi Carti has hardly been absent in the roughly four years since Whole Lotta Red, appearing alongside the likes of Future, Latto, and Trippie Redd in the interim. Still, that didn’t keep his enormous fanbase from persistently clamoring over the prospect of I AM MUSIC, ultimately released with the truncated title of, simply, MUSIC. Its substantial length seems to acknowledge the wait, opening with a flurry of rage-rap tracks like “POP OUT” and “CRUSH” that herald the raconteur’s welcome arrival. Over its 30-track, 77-minute runtime, his sonics shift between the aggressively blown-out, synth-heavy post-trap he became infamous for and something markedly poppier, yet all of it undeniably within his stylistic range. Carti initially kept his choice of guests close to the vest, as has become custom for high-profile album drops. Yet it would be impossible not to recognize Kendrick Lamar spitting on “GOOD CREDIT,” Future emoting over “TRIM,” or collaborative career mainstay Lil Uzi Vert gliding triumphantly through “TWIN TRIM.” The Weeknd’s prominent feature on “RATHER LIE” makes for perhaps the most overt example of his envelope-pushing here, though appearances by Travis Scott on “PHILLY” and the tag team of Young Thug and Ty Dolla $ign on “WE NEED ALL DA VIBES” make the pivot even more plausible. Even with friends like these, Carti shines brighter on his own, his breathy near-falsetto vocal booming through the escalating video game arpeggios of “I SEEEEEE YOU BABY BOI” and his raspy snarl swerving around the cinematic noise of “COCAINE NOSE.” Not exclusively looking towards the future, there’s an almost nostalgic appreciation for Atlanta’s early 2010s sound evoked on “RADAR,” its beat reminiscent of classic 1017 Brick Squad tapes.
