Recently, some urban radio listeners thought they tuned to the wrong dial when they heard Lil Wayne gracing a rock song called Let It Rock. Thanks to Weezys embracing of the Rock genre, Rap-Rock Mash ups are gaining popularity again. To change the pace of the game, Ca$h Money took Weezys lead by signing Kevin Rudolf to their Ca$h Money Records label. No stranger to working with pop and Hip-Hop artists, Rudolf has worked with the likes of Nelly Furtado, Lil Kim, and Timbaland earning co-producing and collaborative credits in his career. Rudolfs album In The City is slated for a November 25th release, armed with collaborations such as Rick Ross, Nas, and of course, Lil Wayne.
