Au4 is an audio/visual creative collective formed in 2004 by brothers Ben and Aaron Wylie in Vancouver, Canada. Inspired in part
by the electronica explosion of the 1990s, and landmark albums by Underworld, Massive Attack, Björk, and Nine Inch Nails, Ben
and Aaron began layering and shaping musical and visual composites, accumulating a body of work that would eventually find its
way onto their debut album On: Audio, and into their technically involved live show On: Visual.
Au4 has released one album, On: Audio in 2006 on their independent label Torn Open Records. Their second album … And Down
Goes the Sky is set to be released in January 2013.
