Alongside his sense of humor, one of Michael Christmas’ great skills as a rapper is a versatility that enables him to tackle different sounds with ease and comfort. L.A. producers Casper and B (who last joined forces with Christmas on the humorous “Sneak”) serve up a riotous beat on “Work Hard” that plays an unexpectedly fitting counterpoint to the Boston rapper’s daily observations and self deprecation. Casper and B whirr through different ideas—interpolating a Busta Rhymes album cut one minute and breaking into the pretty Marc E. Bassy-assisted chorus the next—with the same adaptability that makes Christmas entertaining. Listen to “Work Hard” below.
