Ruth Eckerd Hall hosts a double bill of progressive rock groundbreakers tonight. Symphonic-leaning YES are British purveyors of such classic rock hits as Roundabout and Owner of a Lonely Heart. Grammy-winning 70s guitar whiz Peter Frampton (Baby I Love Your Way, Do You Feel Like We Do, pictured, photo by Denis O'Regan) is touring in support of a new album, Thank You Mr Churchill, approved by CL contributor and music aficionado Gabe Ezchebal, who wrote that its his strongest collection of new material in years and that Framptons guitar playing and songwriting skills have never been sharper. Frampton enthusiastically revisits his hard rock roots and puts a contemporary spin on them ... Highly recommended for the long lost legion of fans Frampton mesmerized with his charisma at the height of the Frampton Comes Alive mania as well as newer converts. Weds., June 9, 7:30 p.m., Ruth Eckerd Hall, Clearwater, $49.50-$99.50.
