The hummable pop number “Wander” opens Class President’s EP Ellipsis.

The Lowell three-piece trots out the familiar loud-quiet-loud to good effect, highlighting the melody in full and partial dress. Does the wandering wander in the real world on highways and byways, or is it a figurative wandering inside one’s own mind? It’s a little of one, a pinch of the other, and an extra helping of both.
