Washington Post:

Marking the 150th anniversary of the composition of taps, about 200 buglers and trumpeters gathered at Arlington National Cemetery to play the “lights out” bugle call. In a touching moment, they fanned out so that the haunting notes came from all quarters of the vast cemetery.

There is nothing so haunting as those 24 notes–Taps.
Taps now turns 150.
It will speak for itself.
