Frank Zappa !!! There are tasteful time changes, and then there are 'show-off' and 'just to be different' changes - that appeal to a narrow range of musicians. With Zappa - you feel like you're tripping and falling while you're still sitting in your chair. Not to mention - his lyrics always annoyed me; I just didn't find that kind of humor funny. But no doubt - he could write and play, especially in wiered time changes.

In fact - on the topic of wierd time in general (I know - I'm deviating from my own post) - I think King Crimson should be near the top also.

And as for pop 'offbeats' that still somehow fit the song - The Police's drummer always impressed.

OK - free for all - let's just change the post to weird and interesting timings : )
