DefRock is a Mill City Legend. Born and raised in Lowell, Massachusetts, Donald J. Maker has literally helped to shape the landscape of Massachusetts Hip Hop for several decades. The lead emcee in the legendary EMC-3 Crew, Def has long been known as one of the illest freestylers ever to rhyme in a Massachusetts cipher. His pen game is equally well known as a writer of scores of songs both as an emcee in EMC and as a solo artist. However, this is just the beginning of the legend of D-Rock. D is also a legendary graf artist, and has been featured in documentaries and several books chronicling his storied carrier with the aerosol. He is now commissioned as an urban renewal artist for the City of Lowell and has displayed his art in numerous venues and exhibitions. Equally impressive is his immense DJ talent as a scratching assassin and break-beat aficionado on the wheels of steel. He is also the "mastermind" behind Monsta Mind Productions, a recording studio and posse of talented artists from Southern NH, where Def moved after leaving his native Lowell. Donnie is also a proud father of Miles Maker, whom he trained as a DJ. The duo perform together for what is a must see show.
