Tacoma’s Old Town Business Association is bringing a free blues concert to Old Town Park on Saturday. Blues On has some of the Northwest’s premier blues performers, including Stacy Jones and Patti Allen & Monster Road. Patti and the band won the 2017 WBS Best of the Blues awards for Best Blues Performer and Best Blues Band. They’ll be the closing act at 6:15 PM, with some fine music leading up to it. The event opens at 1:00 PM with the The Fabulous Roof Shakers. The park isn’t big, so you might want to plan to be there early to get good seats.
