For an eclectic blend of original acoustic music from South America to the blues, Desert Sky Media’s “Singers and Songwriters” concert is a must see at 7 p.m. Friday at the Elks Opera House in Prescott. Angie Raess (pictured), Random Temple, Jerry Kosak, and I Am Tamela play for about a two-hour show. Tickets cost $15 at the door, or online at <a href="http://www.elksoperahouse.com/" target="_blank">www.elksoperahouse.com</A>. “One hundred percent of the proceeds go to the Elks Opera House Foundation,” said Mitchell Pietz, concert organizer. “The musicians are performing for free.”
