Brian Wilson of the Beach Boys has been traveling the world giving audiences a chance to bid farewell to his most celebrated achievement: the 1966 album Pet Sounds. Ranked by Rolling Stone as the second-greatest album of all time, Wilson’s masterpiece helped lift a surf rock vocal group to auteur status in the rock world. Brian Wilson’s tour with fellow founding Beach Boy member Al Jardine, Blondie Chaplin, and his terrific band will be at the Palace in Albany on April 26 at 8 p.m. and at the Hanover in Worcester on April 30.
