Not sure how credible this is, but apparently it already has dates (07/17/15-07/18/15) and a layout (two outdoor stages and one tented stage), and a venue (Foster Farm in Eau Claire, Wisconsin).
JV teaming up with Crashline Porductions (of Boston Calling fame), and expecting ~25,000 people per day.
Line-up speculation if true? Artists he's worked with maybe?
Polica, James Blake, Kanye, Sharon Van Etten, others?
Edit: Proper name Eaux Claire Music and Arts Festival.
