Sage the Gemini makes the kind of hip-hop that could pop off in the club at any time, and his fluid rapping, catchy hooks, and snappy beats provide the rowdy energy that fuels his mixtape Morse Code. He gets bodies moving by skillfully riding the pulsating, dance-floor-friendly grooves of “Come Get It,” while the Kap G-featuring “Cost” is more darkly tinted, as Sage receives a series of mysterious phone calls over the ominous sound of creeping keys.
