They have actually released 5 studio albums, Boston, Don't Look Back, Third Stage, Walk On, and Corporate America. Corporate America was released in 2002, so in 27 years we got 5 studio albums. About one every 5 1/2 years. That's slow. Especially since the first two were only 2 years apart. They are supposedly working on another studio album. Sure. Release date will probably be 2020.
