YBM ( formerly Ya Boy Mass ) is an MC I've known for probably around 5 years, maybe longer. When I did the Graveyard Shift at WSCA in Portsmouth, NH he came on a number of times. But now he's got a family, he's finally getting older, & so he slowed down a little making music but now he's back. He's not Ya Boy anymore, it's just YBM. He's a good dude so definitely look him up.
