Starts at the first one (1993.10.30 - Essential Mix - [URL="http://www.mercuryserver.com/forums/djdb.php?id=155"]Pete Tong[/URL]) and goes to (2011.07.30 - Essential Mix - [URL="http://www.mercuryserver.com/forums/djdb.php?id=104"]Paul Kalkbrenner[/URL])
Credit goes to +Db on Soundcloud. Many are in flac. Very few failed to download. Some I just had to reclick the link manually if DownThemAll! didn't get it the first time.

I used the Firefox plugin, DownThemAll! to get them all at once.
