The Village Voice's 4Knots Music Festival will be back in 2015 but with a few changes. This year it happens on July 11 at Hudson River Park's Pier 84 (where River Rocks was last year) and for the first time will be a ticketed event, with proceeds benefiting the Park. From the press release:

Having this years 4Knots Music Festival at Pier 84 in Hudson River Park ensures we can continue to deliver a great, live, innovative music festival to New York," says Village Voice publisher Josh Fromson. "This location will allow us to create a massive music experience for our fans, while the low ticket price will assist us in supporting the Friends of Hudson River Park. We look forward to seeing you all this Summer on the West Side

No word on this year's lineup but tickets ($25 general admission / $50 VIP) go on presale May 6.
