I see a bit confusion, so here is how it is:
A1. No Return [Push Remix]
A2. No Return [Original Mix]
AA1. Urban Shakedown [Bryan Kearney Remix]
AA2. Urban Shakedown [Original Mix]
Tracks in the sample are the new ones, so its the Bryon Kurney Remix, which just adds more techy kick and the Push Remix, which...actually do the same, just changing the beat and some tweaks in the bassline as well. Since I am a hunge fan of the old Push era, I always prefered the mighty Push kick from 99-04 era. Nothing can top that....
so this release is more for the collectors, the new versions are slightly pointless for me although they are not bad, but well. its a nice bonus
