For Day 2 of Movement Electronic Music Festival, Hart Plaza was filled once again with techno nerds and audiophiles from around the world ready to experience the sights and sounds of the best of underground dance music. Detroit has certainly opened its arms to us visitors — everyone from convenience store owners to cab drivers seem to understand why we’re here and heartily suppose the cause. Even those who could not themselves enter the festival scanned the exterior perimeters of the gates, moving to and enjoying the music in any way they could.
