Dollison and Marsh, Vertical Voices: The Music of Maria Schneider (ArtistShare). Julia Dollison has joined forces with her husband, the singer-arranger Kerry Marsh, to create an album of Maria Schneider’s compositions for big band in which all of the original horn parts are sung, not played. (Schneider’s own rhythm section provides instrumental support.) More than just a technical tour de force, this CD is a miracle of kaleidoscopically varied vocal color that provides an arresting new perspective on Schneider’s musical genius. If you’ve heard Observatory, Dollison’s 2005 debut CD, you won’t need to be told twice to get Vertical Voices. If not, get them both (TT).
