Poor Places has some interesting timing changes. Basically it has every thing a rock song should.
A couple of my faves:
Sleepytime Gorilla Museum - Sleep Is Wrong
3 bars of 15/4, many many of 15/8, several in 3/8, back to more bars of 15/4 for a bit (with a really awesome break near the end of one of the bars), 15/8 again for a time, vamps on 5/4 until the end.
John McLaughlin - Arjen's Bag
Perfect 11/8 for the entire song.
The Bad Plus - The Empire Strikes Backwards
4 bars of 11/8, 4 bars of 23/16, that's as much as I've ever bothered to analyze. These guys are mad.
Mephiskapheles - Break Your Ankle Punk
The main theme goes 4/4 - 3/4 - 3/4 - 3/4. There is part of the solo section that jumps away from the regular 4/4 and plays two bars of 9/8, then a bar of 7/4, then returns to normal.
