For the last couple of years, we’ve had a section of our site called The Bridge which is dedicated to making the connection between old classics and new music. Now, legendary mixtape king Doo Wop has a new project dropping where he does the same by having rap legends and current underground MCs spit together on classic tracks. The first drop features AZ & REKS going in on OC’s Time’s Up beat. Check out Bridging The Gap. Related: Nas performs Life’s A Bitch with AZ at SXSW 2012
