Our interview with the enigmatic Divine Styler starts with him present, via his DJ father, at the very beginnings of hip-hop. He then became a part of Ice-T’s Rhyme Syndicate crew, which included a pre-House of Pain Everlast. His second album, Spiral Walls Containing Autumns of Light, drastically expanded the range of what a hip-hop artist could do with its spoken word-industrial-rock hybrids.

His latest record Def Mask comes after a 15-year hiatus. From NYC park jams to getting arrested the day after signing a record deal to having a front-row seat for “Jump Around“‘s massive success to pushing musical boundaries to making pilgrimages to Mecca, Divine Styler shares his whole fascinating story.

Divine, as he is fond of saying, has gone “from crack to rap to tech.” His wild and inspirational story starts in Newport, Rhode Island, where he started dealing drugs just as the crack epidemic took hold—and also as hip-hop was starting to blossom.

It wasn’t until years later, as he was finding his way out of the criminal life, that Divine let his passion for music take hold, and began his career as a rapper. But a chance meeting over Twitter with venture capitalist Ben Horowitz would take him on a whole new adventure.

Divine is now a coveted speaker at tech events, a startup founder himself, and still an emcee, as anyone who has listened to his 2014 album Ghetto Rhymin’ will attest.
