Kalea Griffith, 23, of Hartford, is no stranger to the sound of steel drums. Her father, Kelvin Griffith, has made all the instruments for the Hartford Steel Symphony, an orchestra made up entirely of steel drums. He also arranges all of the group’s music. Each drum - "pan" in steel-drum vernacular - has a name such as "tenor," "bass," "guitar" or "cello." Kalea plays pan and also is a member of the National Guard. We caught up with the Griffiths during a recent rehearsal at the Trinidad and Tobago American Society of Hartford Inc.
