Most Complex Time Signature ever!?

Complex time signatures can often be broken down into groupings of two three and four beats. In modern classical music the groupings are given in what looks like an alegbra equation over the beat value something like this: 3+2+3 / 4. That would be the equal of 8/4 but tells the player how to "feel" the note groupings. The potential for this type of time signature, as noted, is limitless, but there does need to be a repeat of the basic pattern of groupings. For example, Supper's Ready's Apocalypse in 9/8 would be grouped 3+2+4 / 8., both because that totals 9 and because the pattern repeats over and over. Looked at in this way none of them are really all that complex. It's more about feel than it is about counting.

Some More:

Black Page : Frank Zappa
Red Shift: Anders Johansson
Alex Mahacek: most tracks from his forthcoming album [SIC]  or from his earlier album Featuring Ourselves - check out the merging of Charlie Parker's Donna Lee with Zappa's Black Page.

Joe Morello's Castillian Drums (ex. Dave Brubeck Quartet's Carnegie Hall Live album) is reckoned to go through several dozen time signature changes

I'm unable to read many of Meshuggah's time signatures. They win!

I don't know...13,000/16.  It's limitless...

Maybe:
