By Kayla Asbury A Charleston summer staple is bringing the block-party back downtown this Saturday. The third annual Charleston Area Alliance Downtown Streetfest will return to Capitol Street with its first event from 4 to 9:30 p.m. Saturday, headlined by reggae artist Shayar who will be performing with the Beckley-based band, Krooshal Force. "The goal of Streetfest is to bring people downtown," said Tim Brady, vice president of sales and marketing at the Charleston Convention and Visitors Bureau.
