Tiesto is awsome (number 1 dj in the world
http://www.thedjlist.com/ )
but he isn't even close to the same genera as Shadow. Not in the same ball park, not in the same city, not even on the same planet.
If you like Shadow pick up his live release 'in tune and on time' It's a 2 disk set. 1 dvd where you can watch him perform an entire set (somewhere in the UK) it's absolutely amazing. And 1 full length CD. So ill.
Also his new one Private Press is sick.
If you're in to this kind of musick i recomend the documentary 'Scratch'. Shadow has a pretty big segment in it.
