Aj Ross has 5 Gramatik concerts.

Good music is felt not heard. Gramatik apparently understood that at an age of 3 according to his mother as she used to catch him glued to the radio in his older sister's room whenever there was an old funk or rhythm & blues joint on, tapping his leg on the floor along with the beat. Damn, talking about a sign on what will your child do when he grows up!
