Like many of the other acts at the Memphis Music and Heritage Festival, I had not heard of Artistik Approach prior to last Saturday, but I was extremely impressed with their talent and artistic vision. Artistik Approach is basically a rap group, but one member accompanies the lyrics of the other with beat boxing rather than using prerecorded tracks, which makes the act both unique and self-contained. And despite the limited sonic palette, they can hold an audience spellbound.
