Here's what Andy Mitchell has said about his own composition Drift recorded on Ex Tenebris...Lux:
"Valerie plays Drift with a gentle, sensitive dynamic contour and achieves great separation when defining the different voices. Her color variation and expressive phrasing really help to emphasize the pensive character I intended when writing Drift."
