Dierks Bentley will be the main attraction Saturday night at the Puyallup Fair & Events Center grandstand. You can expect some “What Was I Thinkin’,” some “Sideways” and maybe some “Feel That Fire” on the set list. But along with the big radio hits, expect a few unplugged selections from his latest critically acclaimed album “Up On the Ridge.” There’ll be a related Q & A in Friday’s GO section, but until then click here to listen to the country superstar talk about why he went bluegrass on the new CD.
