The sleepy town of Hilo might not be described as urban, but big city music clearly has fans there. Hip-hop legends Naughty By Nature are coming to the Big Island for what what is billed as the inaugural "Urban MusicFest." The group will be joined by local artists Sudden Rush and Times Five. The concert will be held April 17 at the Afook-Chinen Civic Auditorium, and tickets go on sale next week for $25 at Big Island music stores CD Wizard in Hilo and Melekai Music in Kona. Admission at the door will be $30. Concert organizer R&R Productions hopes the all-ages, alcohol- and drug-free concert will become an annual showcase of "hip hop, rap, rock, R&B, and reggae."
