I made an unofficial mash-up of these two beautiful tracks:
Gareth Emery feat. Activa - All Is Now (Jorn van Deynhoven Remix) and Super8 & Tab feat. Jan Burton - Empire.
This is a short edit, check out http://soundcloud.com/darude/gareth-emery-vs-super-8-tab for the full length mix.
I frequently make edits and mash-ups of tracks for my own use, but I never post them anywhere without approval, so I'm delighted that I've gotten big thumbs up from the original makers and both labels Garuda Music and Anjunabeats have stream-approved it for me. Gareth himself already played it in his podcast + numerous other top jocks around the world are playing it in their live sets and radio shows, which I'm really happy about, of course! :)
