One of the longest-lasting and most beloved music festivals in Europe, Rock Werchter will celebrate its 50th anniversary the first weekend of July at Festivalpark in Werchter, Belgium— Werchter was a festival R.E.M. always looked forward to, playing it a total of 7 times (and in fact, from 1985 on, every single summer tour by the band in Europe always had Rock Werchter anchored in the schedule.) To commemorate this milestone for the festival, Belgium’s Flemish language public broadcaster VRT will release a documentary “50 Years Of Rock Werchter, As Seen Through The Artists’ Eyes.” And thanks to Pieter Verbiest and Gianni Marzo, directors of the film, we can share this sneak-peek into their creative vision, featuring some tremendous performance footage of R.E.M. in different years and typically insightful commentary from Mike Mills.
