Ever the Optimist, the name of the seventh album from Scottish indie-pop institution the Trashcan Sinatras, appears to be the kind of title that should be delivered with a wink or a smirk. But the Trashcan Sinatras belong to the waning years of the 20th century, and they don’t do irony, nor do they chase trends. The music is bright, relaxed, and natural, with the Trashcan Sinatras revving up the tempo just enough to give the album a bounce. But the Trashcan Sinatras also populate the album with songs about loss and absences, ending the on the meditative note of “Learning to Love Your Ghost.” The presence of the additional voices enhance the sense of camaraderie on Ever the Optimist, how the Trashcan Sinatras are summoning their good spirits by relying on music that has never let them down.
