They just keep rolling out these lyrical piano players for us to admire. Nelda Swiggett is first a pianist and composer. She sings her own lyrics on three tunes, but instrumentally, she writes and plays with attractive melody lines and in many cases, a buoyancy not always heard these days. With her playing mates Chris Symer on bass and Byron Vannoy on drums, Ms. Swiggett has produced a versatile pallet of songs, all which land attractively on the ear.
