Maffew Ragazino and PUSH!’s “Jane Fonda” should be reserved for those who really like rap. Not the radio kind or the stuff that’s predictably formula driven. Nah, these two Brooklynites talk real strong and they all but have to. ATG’s production creates an eerie like the type of music that played in the background when Scooby and Shaggy were on the prowl for ghouls and ghosts. Weak rap won’t survive that, but PUSH! and Maffew Sr. slide through cleanly.
