program notes: "Luminosity" was commissioned by the River City Brass Band to commemorate the 250th birthday of the city of Pittsburgh, founded November 25th, 1758. The title (a pun on "luminous city") alludes to the bright, shimmering character of the music created through rich, lively brass textures, and the colorful interplay of piano and mallet instruments (vibraphone, xylophone, marimba, glockenspiel, crotales).
press bytes: Galbraith's work, "Luminosity" is the last of a collection of commissions from the band to celebrate the city's 250th anniversary. She says it is a play on the words "luminous city," and she wanted to depict how the city sparkles because of its people.
  She succeeds in creating a dazzling piece with clever melodic lines that are challenging but never hard to listen to. — Pittsburgh Tribune-Review.
