This is starting to look like a major disappointment.
From the blurb on the website, this appears to have very little to do with getting high and enjoying great music with friends in a nice park. In other words, nothing like Vortex was.
The Vortex name has been hijacked for misuse by commie programmers.
The focus seems to be on socialist activism, signing people up to push socialist views, and getting media attention for socialist causes. Oh and they say they'll have some music too.
I'll probably avoid it and be even more satisfied with my memories of the Real Vortex. Brown Sugar, Jacob's Ladder, Charlie Musselwhite...
