What immediately strikes one upon listening to Vox One's new "Pure Imagination" CD is how good they are not in a flashy, notice we are brilliant singers kind of way, but in a deeply felt, technically beyond question, born to sing way that shows us all of us lesser talents how its done. After seven years, one of a cappella's most accomplished (and recognized) vocal jazz groups returns to the CD player with a satisfying collection of originals, covers and improvs. Yes, Vox One has matured and is exploring new styles, including Indian ragas and world music tinged vocal jams. For those loyal listeners who loved "Chameleon," "Out There" and "Say You Love Me" and have been waiting for an encore, there are the standards such as "Pure Imagination" (written by Leslie Bricusse and Anthony Newley), and the traditional "Aura Lee," but there are plenty of new songs composed by the group, as well as the six improvised tracks that offer plenty of room for the the five members (Yumiko Matsuoka, Paul Pampinella, Paul Stiller, Jodi Jenkins Ainsworth and Tom Baskett) to stake out new vocal territory. These Berklee College of Music faculty members exemplify what it is to harmonize, blend and intonate with sublime perfection, and we thank them!
