In a statement released by A State of Trance just hours before his set, Dash Berlin was pulled from the ASOT 850 Poland lineup due to what’s being called “health-related issues.” In his steed, label boss Armin Van Buuren is filling in with a three-hour set. As a mini tribute, Van Buuren played Dash’s iconic song ‘Waiting‘ on the main stage. 30-minute live streams of each artist can be viewed here on Facebook.

While no further details have emerged, the Polish crowd was stunned to learn the news. They took to social media immediately to show support for Jeff (aka. Dash Berlin), expressing their well wishes. Dash was set to return to ASOT following a four year absence. His last performance was at ASOT 650 in Utrecht in February 2014.

He has been reviving his old school trance sound of late on his Legend of the Feels tour, and was going to play a “Classics” set at ASOT 850. His classics set at the Quantum Valley stage of EDC Las Vegas last week nearly brought the structure down. Trance fans flocked to hear him take a dive back to his original sound.

If he is recovered in time, fans can next catch Dash June 15 at Exchange Los Angeles for his next Legend tour date. I know I speak for all of us when we say – GET WELL SOON, JEFF! Checkout his ASOT 650 set from Utrecht below.
