A larger, much more interesting set from at least one 2013 Naked Heart, and/or possibly a 2014 one. Same photographer, also recently uploaded. There are many more women in this set, and it may actually be from two different events, or might be from multiple photoshoots at the same event. I haven't gone through carefully, but some of the people in the riverside portion of the set are also in the stands later and some aren't, but there are many new people in the later portion. I noticed that some of the women in the stands were from Gerrit's earlier-posted video (vimeo.com/135495568), which he has labeled "@ Frequency Festival
2014." The first attachment is from the thumbnail of that video, and the second is a detail of "43963748101.jpg", from this set. Regardless of when and where the event(s) was/were, there's a lot to enjoy here.
Edit: I just noticed this post pushed my also-new post of
2016 photos off the page. This 2013 (or 2014) set is much better, but the 2016 one is good, too, so you should check it out.
