It’s been about 40 years since the 16-year-old Queens rap hyena LL Cool J released “I Need A Beat,” his classic debut single, on the newly founded label Def Jam Recordings. It’s been eight years since LL released his most recent single — “You Already,” a collaboration with the currently-incarcerated Troy Ave. Lately, LL has been too busy raking in NCIS money to focus on his rap career. Last year, though, LL took part in lots of the festivities around hip-hop’s 50th anniversary, including headlining his own all-star old-school Rock The Bells tour. Now, we’ve got a new LL Cool J single that works as a grown-man rap summit meeting.
