Query: The boy can BLOW...

I am so impressed w/ Calvin. I wasn't really up on game when it came to him. I saw his videos and thought, oh another R&B dude, trying to sing to the ladies. But oh my goodness. I was stumped when I saw the movie "Deliver us from Eva" and heard his song "More than a woman" in the background. I thought, dag, that is a hot song. And who is singing that!? I immediately went online and found it was him. I listened to a couple of samples and took a chance on him, and WOW! I love his voice. When he sings, I find myself nodding my head saying, "Sing boy!" One can tell if the artist trully feels what their singing. And I really admire that about him. He draws you into his story. You've got to give him a chance. He's mad talented. And under played. As always, this is one for the archives!
